You’re not alone if you’re dealing with a screeching sound from your laptop speakers.

Several factors can cause this common issue, but the good news is that it can often be fixed quickly and easily.

In this article, we’ll provide you with some practical solutions to help resolve the screeching sound from your laptop speakers, so you can get back to using your computer in peace.

Why are my speakers making a screeching noise?

There are several reasons why laptop speakers can produce a screeching sound. Here are some of the most common causes:

Damaged speakers – Physical damage to the speakers can cause them to produce a screeching sound. This can be due to being dropped, bumped, or otherwise impacted.

Loose connections – The speakers may be loose or not correctly connected to the laptop, causing the sound to come out distorted.

Outdated audio driver – An outdated audio driver can cause compatibility issues that lead to a screeching sound.

Background noise – Other programs or processes running on your laptop may interfere with the audio output, causing a screeching sound.

Malware infection – Malicious software can cause various audio and performance issues, including a screeching sound from the speakers.

Overloaded audio system – Playing high-quality audio on a laptop with limited resources can cause the audio system to become overloaded, leading to a screeching sound.

Faulty hardware components – A malfunctioning speaker or audio card can cause the speakers to produce a screeching sound.

Volume levels too high – If the volume on the laptop is set too high, it can cause the speakers to produce a screeching sound.

Now we are past possible triggers, let us explore some solutions.

How can I fix the screeching sound from laptop speakers? 1. Run the audio troubleshooter 2. Perform a clean boot

Performing a clean boot for your computer reduces software-related conflicts that can bring up the root causes of the computer screeching sound.

These conflicts can be caused by apps and services that generally start and run in the background when Windows starts.

You will have a clean boot environment after all these steps are carefully followed, after which you can try and check if the computer screeching sound goes away. If not, try the following solutions.

Can’t open Task Manager? Don’t worry; we’ve got the right solution on how to open Task Manager in Windows 10 or Windows 11.

3. Reinstall audio drivers

If you lack time to go through every single troubleshooting tip mentioned below, there’s a shortcut that you need to know about from the very start.

Well, it involves uninstalling and reinstalling your audio driver. In this case, you can complete the procedure by following the above steps.

However, let us remind you that downloading drivers manually may cause conflict with the PC. It’s enough to make a simple mistake and install the wrong one.

That’s one unfortunate scenario only, yet many things can happen when you’re not mainly used to such procedures. So, don’t hesitate to install the Outbyte Driver Updater tool to prevent all potential issues.

Let us tell you more about how it works. Instead of worrying about making the right choice, Outbyte Driver Updater performs an efficient scan for you from a database of over 18 million drivers.

Later on, it does what knows the best – you can see how the download is progressing, and before updating your audio drivers, the app will even perform a quick backup for safekeeping.

Reinstall all drivers automatically with this dedicated software with a comprehensive scan.

4. Update audio drivers

Expert tip:

5. Use the generic audio driver 6. Replace your hard drive

Before you replace the drive, back up all your data from the computer, as the damage may cause data loss.

Replace your drive ASAP after backing up your data, then restore it to your computer.

If it is the fans’ fault and not the hard drive, take off the side case and check if all fans are rotating. If there’s a dead one, you can replace it quickly and affordably.

While the side is open, you can also vacuum clean all air vents to remove any accumulated dust.

7. Check volume and BIOS settings

Sometimes the playback recorder may be set to Listen to this device, and this, along with mic amplification, can be set higher than usual, causing a feedback loop.

So the computer screeching sound you hear is an amalgam of the cooling fans, system sounds, and other ambient noises recycled through the mic and amplified continuously through the speakers.

Change the range of sound from high to optimum for the speakers to output.

You can also check your BIOS settings as sometimes – and on different computers – this is set to alarm when the CPU hits a specified level (degrees).

You can raise or lower this threshold and see if the computer screeching sound goes away.

Another reason for the computer screeching sound is your frame rates may be too high for the monitor, so you need to check the monitor refresh rate, usually at 500-60Hz, and set yours to match.

This will stop the noise from the capacitors on your graphics processor unit (GPU).

Hotmail Not Receiving Emails? Try These Fixes

Throughout the transition from Hotmail to Outlook, Microsoft has maintained the reliability of this email client. However, it’s normal to run into some errors sometimes.

If you’re not receiving emails in Outlook, it’s probably because of some changes in the settings. Or, it can sometimes happen when Outlook’s server is down. Either way, here is an article on how you can fix this error. 

Mostly, you won’t see the received emails when Outlook detects an email as junk. The Junk email filter is enabled by default, and it can sometimes mistake a safe email as junk. But, there can be other reasons for this issue too. Some of them are listed below.

Mail is in other folders

Filtered Inbox

Blocked senders

Email rules

Email forwarding

Blocked Account

Issue with Sender’s mail

Bad Internet Connection

Interference by Anti-Virus

Before you try the other fixes, you can re-login to your Hotmail account to see if it fixes the issue. Also, you can check if Outlook’s server is down. If the server is offline, waiting is the only option. If that’s not the case, you can try the other fixes.

Some emails end up in your junk folder. So, it’s best to check it, and if there are emails in the junk folder, you can mark them as not junk. To do so, follow these steps.

Also, check the other folder if you use focused emails. In the Inbox folder, go to the Other tab and check if the emails appear there. You can move it from Other to your Focused email. To do so, you can follow these steps.

The emails that appear in your Inbox folder may be filtered or sorted. You can change the filter by following these steps.

You may not receive emails if your outlook storage is full. On a free account, you have 15 GB of storage. To check how much space you have left, follow these steps.

If your storage is full, you will have to clean up by deleting some emails.

Outlook Rules allow you to automatically flag, move, reply to, and delete some emails. When it is set up incorrectly, your emails can move to other folders automatically, so you won’t see them in your Inbox. To change, turn off, or delete Rules, you can follow these steps.

Email forwarding sends the emails that you receive to another account. If this is turned on, you may not receive emails. To turn it off, you can follow these steps.

When the temporary data saved by the browser and the latest data don’t match, it can cause issues with certain websites. So, it’s best to clear the browser cache, cookies, and other site data in this case. To do so, follow these steps.

On Chrome

On Firefox

This issue can also prevail if you’re using an outdated browser. To update your browser, follow these steps.

On Chrome

On Firefox

If you have a Hotmail alias, you may want to add an Outlook Alias to your account. When you do this, you will receive any mail sent to your alias. And you can also log in to your account using your alias. To add an Alias, follow these steps.

Sometimes, your Antivirus can also interfere with your emails. You can disable your Antivirus to check if it’s interfering.

To disable the Windows Defender, follow these steps.

If these fixes did not work, you can contact the sender and see if the issue was caused by their end. You can ask them to resend you the mail and check if they have any issues.

If none of these worked, you have no other option but to contact Outlook Support to look into your account. To do so, follow these steps.

Edgar Cervantes / Android Authority

With over 48 million subscribers across its on-demand and live TV plans, Hulu is one of the largest and most recognizable streaming services. However, even with such a large subscriber base, Hulu isn’t immune to issues. Let’s take a look at what you can do if you find Hulu not working for you.

Editor’s note: Some of the instructions in this article were generated using a Google Pixel 7 running Android 13, an Apple iPhone 12 Mini running iOS 16.4.1, and a custom PC with Windows 11. Keep in mind that steps can be slightly different depending on your device and software version.

Is Hulu down?

Keep streaming limits in mind

Robert Triggs / Android Authority

A Hulu subscription is meant to be for a single household. As such, the service doesn’t want you streaming on many devices simultaneously. This could be the reason for Hulu not working for you.

Is there anyone else using your Hulu account? Maybe more than one other person? Hulu only allows you to stream with two devices simultaneously. If you want to stream on your device, you’ll have to ask other users to stop streaming.

Also, you might want to get the Unlimited Screen add-on, which is only available for Live TV subscribers. It costs an extra $9.99 a month, but it will allow you to stream live TV on as many devices as you wish. These should be within your same household, but Hulu understands sometimes you want to watch content on the go. With the Unlimited Screen add-on, three of the devices can be mobile devices in other networks.

Try a simple restart!

Restarting the device is one of the most popular troubleshooting methods around. I always recommend it to friends and family whenever they come with tech problems. It turns out a simple restart seems to fix most issues, so give it a try!

How to restart an Android phone:

Press and hold the Power button.

Select Restart.

Learn to restart your iPhone:

Press and hold the Power and Volume Up buttons until the power screen appears.

Use the slide to power off slider.

When the phone is off, press and hold the Power button until the Apple logo shows up.

How to restart a Windows computer:

Select the Power button.

Pick Restart.

How to check for Hulu app updates on Android:

Open the Google Play Store.

Tap on your profile icon.

Select Manage apps & device.

Pick Updates available.

If Hulu shows up, you can select the Update button next to it. You can also tap on Update all to take care of all your updates in a single sweep.

How to check for Hulu app updates on iOS:

Launch the Apple App Store.

Tap on your profile icon.

You should see all available updates here. If Hulu shows up, select Update next to it. You can also hit Update All to take care of all your updates in a single sweep.

Update the device

Open the Settings app.

Go into System.

Hit System update.

Tap on Check for update.

You’ll be told if there is an update available. Suppose there is, select Download and install.

Follow instructions and let the phone update.

Try using Hulu again!

Updating your iPhone:

Launch the Settings app.

Go into General.

Tap on Software Update.

The system will automatically look for updates. If there is one, tap on Download and install.

Your device will let you know if there are any extra steps to take. Follow the instructions.

How to check for Windows updates:

Open the Settings app.

Go into Windows Update.

Updates will start downloading if available. Some are optional, and an option will appear if they are. We recommend you get them too.

Some updates require restarting the device. The page will tell you if that’s the case. Go ahead and restart if needed.

Let the computer do its thing. It will restart after it’s done updating.

Now check if Hulu is working!

Open the Settings app.

Go into Network & internet.

Under SIMs, select your primary network.

Toggle Mobile data on.

If you’re outside your country or network coverage, also toggle Roaming on (this may incur extra charges).

How to turn on mobile data on iOS:

Open the Settings app.

Go into Cellular.

Toggle on Cellular Data.

If you want to turn roaming on, go into your main network under SIMs and toggle Data Roaming on (this may incur extra charges).

Is the network blocking Hulu?

Edgar Cervantes / Android Authority

Those using a public network or someone else’s Wi-Fi might be facing a network block. It’s common for administrators to block streaming services, including Hulu. This is often the case when you use a worried parent’s Wi-Fi, or when using the internet in a library, school, etc.

If this is why Hulu is not working, your only solution is to ask the administrator to lift the ban on the service. Or you can move back to your own mobile data.

Check your device location and VPN settings

Edgar Cervantes / Android Authority

All video streaming services have geographical restrictions, but Hulu is especially known for its strict location rules. The service is only available in the USA. This includes Puerto Rico and US military bases.

If you’re anywhere outside USA borders, then that’s why you’re having issues with Hulu not working. Your only real solution is to go back to the States. If you’re on a military base, and Hulu tells you you’re outside the USA, you can contact support to get everything sorted.

Additionally, those using a VPN for security or location purposes might also come across issues. Streaming services don’t like VPNs and have ways to detect them. This means that you might be blocked off Hulu if you’re using a virtual private network, even within the USA.

Common Hulu error codes

Are you getting an error code? We know how confusing these can be. Let’s take a look at some of the most common ones and try and find a solution for them.

How to fix Hulu error code p-dev340

This usually signifies a problem with the device or the internet connection. You can try restarting, reinstalling the app, updating the app, or checking your network. Clearing the cache may also help.

How to fix Hulu error code p-dev318

This code shows up when there are connection problems. Try to see if your internet is working, make sure mobile data is on (if you’re using a cellphone), or check if Hulu is down.

How to fix Hulu error code p-dev301

This is a playback error, and is usually a problem on Hulu’s side. It can also be caused by an outdated app, or a faulty internet connection, though. Update your app and check your internet connection.

How to fix Hulu error code 137 on Samsung TV

This error code seems to show up pretty often with Samsung TVs, and not only for Hulu. It just means your device is having issues connecting to Hulu. This could be due to a weak internet connection, slow speeds, an outdated app, or faulty cache files. Try clearing the cache, updating the app, and making sure your internet is operating correctly.

How to fix Hulu error code 137 on Samsung TV

This is usually an issue with Hulu’s servers. Check if Hulu is down. If it isn’t, the issue is probably your internet connection.

How to fix Hulu error code 21

Hulu sends this error code when it notices a drastic change in your internet connection. You may have switched networks, or moved from Wi-Fi to cellular. The easiest solution is to close Hulu and reopen it. It’s not a big problem, usually.

FAQs

You can download Hulu content for offline watching only if you have a No Ads plan.

Hulu plans are meant to be for a single household. This is why the plans only allow for two simultaneous screens streaming. If you have a Live TV plan, you can also pay for an Unlimited Screens add-on, which costs $9.99 monthly.

Hulu has 4K content available, but not everything has this higher definition. Most Hulu original content is available in 4K. Syndicated content is usually limited to HD.

Can’t Join Minecraft World? Try These 9 Fixes

When all you want to do is play Minecraft, the last thing you want to see is an error: “Unable to connect to world.” There are multiple reasons for this error message, but the good news is you can correct most of them quickly.

If you can’t join multiplayer games with your friends, here are a few things to try to get you out of the menu screen and back into the depths of the latest Minecraft update.

Table of Contents

1. Restart Your Computer

2. Check Your Internet Connection

Sometimes your PC or console might show you connected to the Internet, even when you aren’t. This often results from a faulty or intermittent connection. If you can’t join your friend’s Minecraft world, check your internet connection or perform a speed test using something like Ookla Speedtest. This gives you the clearest picture of your current network status and speed.

3. Make Sure You’re Using the Same Edition of Minecraft

There are two editions of Minecraft: Bedrock and Java. These two editions are not cross-compatible, but a recent announcement from Mojang and Microsoft provided owners of one version with a free copy of the other. Just make sure you and your friends are playing on the same edition, or you won’t be able to join one another.

4. Update Windows and Minecraft

Software updates do more than just add features; they also fix bugs and other glitches. If you aren’t running the most up-to-date version of Windows, then you might not have the latest network drivers. You should also make sure you’re running the latest version of Minecraft. While the game should automatically update, you can also download the latest version of the Minecraft launcher from the official website.

If an update is available, select

Restart Now

to update your computer.

5. Re-Add Your Friend

One fix is to remove your friend from your friends list and add them back. This works because Minecraft stores friend data on the server, not locally. That’s why you’ll have the same friends list no matter what device you use to play.

Remove your friend from your list, re-add them, and then attempt to join their world. This step will often correct if there is a server issue or mismatched data between your account and the server.

6. Turn Off Windows Firewall

Your firewall protects your PC from malicious connections and boosts your online safety. If your firewall is malfunctioning, it can prevent you from connecting to a friend’s world and sometimes won’t let you launch Minecraft and other online games. The easiest fix (at least for testing purposes) is to disable the firewall.

Select

Turn Windows Defender Firewall on or off

.

Shutting off your firewall will open your system to attack, but antivirus software can help. You shouldn’t leave the firewall disabled too long, though. Disabling it is a great troubleshooting step and might get you back into a gaming session. But be sure to turn it back on after you finish playing or if you find the firewall isn’t the problem, turn it back on immediately.

7. Change Your Firewall Settings

If you discover that your firewall is to blame for your connection issues, the next step is tweaking the settings to allow you to play without endangering your system.

Select

Allow an app or feature through Windows Defender Firewall.

Scroll down until you find chúng tôi Ensure that both the

Private

and

Public

boxes are checked, then select

OK

.

8. Change Xbox Privacy Settings

If you’re playing on Xbox, the problem might lie in the permissions you’ve granted to the game or your profile. Make sure you’ve set your profile to allow you to play multiplayer games.

Ensure

Allow

is checked beside

You can join multiplayer games.

Select

Submit.

This will provide the necessary permissions to Xbox and your Microsoft account to allow you to play on consoles.

9. Use a VPN

A virtual private network (VPN) can fix many issues you might run into when playing Minecraft, but it can also introduce latency. This can be a problem if you’re playing on a competitive server and need every bit of response time possible.

On the other hand, a VPN can bypass geographical restrictions and let you play with friends you might not be able to otherwise.

Whether you’re just joining a friend’s world or jumping into a Minecraft server, multiplayer makes the game much better. If you’re running into issues connecting, make sure the problem doesn’t lie with your Wi-Fi or Xbox Live, and then run through this list to look for other potential fixes and get back to exploring with your pals.

Is Your Macbook Screen Flickering? Try These 10 Fixes

Table of Contents

1. Restart Your MacBook

When you restart your MacBook, all running applications, processes, and services are shut down and then started up again, which can refresh your system and eliminate any transient glitches causing the issue.

2. Check for macOS Updates

From there, select General and then Software Update. This will bring up a list of available updates for your system. If any updates are available, select the Update Now button to download and install them.

3. Disable True Tone

Then choose Displays. In the Displays preferences pane, you will see the option for True Tone. Toggle the switch next to True Tone to turn off the feature.

True Tone is only available on newer MacBooks with a built-in light sensor. If your MacBook is older, you won’t have the True Tone option in your display preferences.

4. Disable Variable Refresh Rates for External Monitors

Make sure your external display is selected from the diagram at the top of the window, then next to Refresh Rate, ensure that Variable Refresh Rate isn’t selected.

We’ve only seen the variable refresh rate feature appear when using DisplayPort output from our MacBook, and with every reboot, it defaults to a variable refresh rate. Until Apple addresses this, you must turn off the variable refresh rate after every reboot or switch to HDMI.

5. Disable Graphics Switching

To disable graphics switching, go to the Apple menu and select System Preferences. Then, select Battery and select the Battery Tab. Deselect the automatic graphics switching checkbox. If you’re on macOS Catalina or earlier, the setting is under the Energy Saver preference tab instead.

6. Reset NVRAM/PRAM and SMC

For more information on how to perform this reset, please read How To Reset PRAM & SMC On Your Mac

7. Restart In Safe Mode

For more information on how to boot your Mac into Safe Mode, please refer to How to Boot Up and Use a Mac in Safe Mode.

8. Run Apple Diagnostics

Apple Diagnostics is a built-in tool that performs a series of tests to check your MacBook’s hardware, including the screen, graphics card, memory, and hard drive.

Once Apple Diagnostics starts, follow the on-screen instructions to run the diagnostic tests. The tests may take some time to complete, but they will provide a report on any issues. If any hardware problems are detected, the report will provide information on the issue and how to resolve it.

You can run Apple diagnostics from the startup options window. To access the startup options window on your Apple Silicon Mac, simply power it on and keep pressing the power button until the window appears. You’ll know you’ve reached it when you see a gear icon labeled Options. Once there, press the Command + D keys on your keyboard to proceed.

For those with an Intel processor, the process is different. Immediately after powering on your Mac, hold down the D key on your keyboard until you see a progress bar or are prompted to select a language. This will take you where you need to go.

9. Run Maintenance Scripts

Over time, your MacBook can accumulate temporary files and other data that can cause issues with performance and stability.

While running maintenance scripts using the Terminal app is straightforward, it can be intimidating for users unfamiliar with command-line tools. Fortunately, third-party applications, such as CleanMyMac X, can simplify the process of running maintenance scripts.

Aside from CleanMyMacX, several other third-party applications are available that can help perform maintenance tasks on your MacBook. One such app is Onyx, a free donationware utility that provides a user-friendly interface for running maintenance scripts and performing other tasks, such as deleting cache files and repairing disk permissions.

10. Take the MacBook Back to Apple

If your MacBook is still under warranty, you may be eligible for a repair or replacement at no additional cost. Apple provides a one-year limited warranty on all new MacBooks, and you can also purchase AppleCare+ for extended warranty coverage within that first year. AppleCare+ provides up to three years of additional coverage and includes two incidents of accidental damage coverage.

In some cases, even if your MacBook is out of warranty, Apple may still cover known problems with Macs through a special program. These aren’t always widely published, but the Apple technician will let you know if you’re eligible for such a program. So it’s still worth bringing your laptop in for an assessment, even if you don’t intend to pay for a repair out of your pocket.
