Suggested January 2024 How To Fix “No Audio Output Device Is Installed” Error
The error message “No audio device is installed” indicates the Operating System is having trouble identifying an audio device which results in no audio output from the computer. Due to unknown reasons, the audio output device gets disabled, sometimes even after a major Windows update. If that’s the case for you, we can simply fix the issue by enabling it.
However, that may not be the only reason the error “No audio device is installed” is displayed. Here in this article, we have listed some other reasons that can cause the error and solutions to fix the issue.What Causes “No audio output device is installed” Error Message?
Here is a list of reasons the Operating System has issues on detecting the audio output device.
Audio output device disabled
Corrupted driver files
An issue with Windows Update
Outdated driver or Windows
Faulty sound card
Wrong Registry Entries
Now that we know what can stop the OS from detecting an audio output device, let us get right into how we can fix the issue.Fixing “No audio output device is installed” Error
Before we start, let us see if the computer is detecting the audio drivers. If not, then the issue is most likely with the audio drivers.
Please follow these steps to verify that the installed sound drivers and device is actually recognized.
Press the Windows + R key and type “dxdiag“ and press Enter.
Go to Sound tab. Here, check for Device and Drivers.
If the system recognizes the sound card and driver, its Name, Version or and the Hardware ID will be displayed.
Perform Solution Update/Roll Back Drivers if the system is not detecting the driver.
Here are solutions that you can try to play sound from the computer once again.Enable Disabled devices
When we update Windows, many settings can get changed due to unknown reasons. Similarly, one of the changes is a disabled audio output device. Once disabled, if the computer is not connected to another audio output device, it cannot produce any sound.
For Windows 10,
Now, once the Sound Dialog box opens, follow these steps.
Once we enable the speaker, the OS should detect the audio device.Run the Audio Troubleshooter
The troubleshooter utility in Windows allows users to pinpoint and fix errors with components like the network adapter, internet, microphone, display, and audio. If enabling the audio device does not work, running the audio troubleshooter can figure out what is causing the issue and suggests possible solutions to fix the problem.
The steps mentioned below will guide you in the troubleshooting process.
For Windows 11,
For Windows 10,
Once we run the Troubleshooter follow these steps
The troubleshooter may or may not display the same process as above. The steps that the troubleshooter displays depend on the type of issue you face. Therefore, after step 6, you may not get the same troubleshooting steps.Scan Hardware Changes
Sometimes, due to unknown reason, the system may have difficulties in detecting audio devices and driver. If this is the case, we can scan the hardware for any changes to bring the driver back and make the device-detectable again.
We can follow these mentioned steps to scan for hardware changes.
Similarly repeat the same steps for Sound, Video, and game controllers and System devices.Run SFC Command
The SFC or the System File Checker command is responsible for finding and replacing any corrupted or missing system files. As driver files are also system files, any corrupted sound driver files can be fixed using the SFC command.
The following steps will guide you in running the SFC command.
Press the Windows + R key simultaneously to open Run.
Type “cmd” without a quotation mark and press Ctrl + Shift + Enter to open Command Prompt as administrator.
Now type “sfc /scannow” without quotations and press Enter.
Now the command will check for any corrupted system files and fix them. It will take a few minutes to complete this process.Check for Hardware Issues
If you are on a desktop computer, the port or cable that connects the speaker to the computer may be damaged. Try connecting the speaker to another computer and make sure that the speaker works without any issue. If it works there may be some issue with the ports on the computer.
We can also check for dust settlement on the 3.5mm jack that may be stopping the connection. Also, make sure that the 3.5mm jack is plugged in the right port, i.e., the speaker port. If connected to the microphone port, the computer will not detect the output device.
Any damage to the Speaker cable can also stop the system from detecting the speaker. So, make sure that there are no visible damages to the cable.
The system will also have an issue detecting the audio output device if we connect the 3.5mm jack to the wrong port. The 3.5mm microphone jack is pretty similar to the 3.5mm speaker jack and it can be mistaken. If so, the system will not detect an audio device.
Also, ensure that the headphone jack is completely inserted onto the port as a loose connection can also cause this issue.Change Registry Values
Wrong changes in the Registry values can also stop the OS from detecting the audio driver. The Windows Registry contains all the Internal OS settings like registry keys and value data. Therefore, a small change in the registry can cause the “No audio output device installed” error message.
However, we need to be very careful while changing any values inside the registry, as wrong changes can slow down the OS or even render it useless in some cases.
Backing up the registry is always recommended before making any changes to it.
Follow these steps to back up the Windows Registry.
Now that we have created a backup. Let’s change the registry values to fix the audio issue.
Open the Registry Editor by following steps 1 and 2 from above.
Now, on the right panel, check the Data column from ConsoleSecurity. If this value is (zero-length binary value), continue with the following steps. However, if the value from ConsoleSecurity in the Data column is a set of two numbers, proceed with another solution.
Close the Registry Editor dialog box and run Command Prompt as administrator.
Enter the following command and press Enter.
Above command will replace previous value from ConsoleSecurity in the Data column to sets of two integer numbers.
Once the process is complete, restart your computer.Update/Rollback Drivers
The Operating system (OS) to communicate with any devices requires a specific device driver. If this driver is not up-to-date, issues can arise when the OS tries to connect to the device. Therefore, updating sound drivers can fix the problem that we face.
There are multiple audio and speaker drivers, so we will need to update all of them. Here is a list of drivers that we need to update.
All audio drivers inside Sound, video and game controllers
High Definition Audio Controller, located inside System devices
Sometimes, the OS will also face issues while detecting audio drivers when connected to an external monitor through HDMI. Therefore, we may even have to update drivers such as the Display Audio driver (located inside Sound, video and game controller).
If automatically updating the audio drivers does not work, we can also use the audio-chip-manufacturers download center to get the latest driver. Most motherboards use Realtek HD audio drivers. We can use its download center to get the latest driver and install it manually.
For Intel audio drivers are packaged into the graphics driver. Therefore, if you are an Intel user, download the latest graphics driver from Intel’s Official Download Center.
As for AMD, we can download the latest audio driver which is also embedded onto the graphics driver in AMD’s Official Download Center.
However, updating the driver to the latest version may not be best as sometimes, a driver update is also known to bring in some bugs to your system. If that’s the case, we can always roll back a driver update. The following steps will guide you through a driver roll-back process.
If updating and rolling back the driver does not fix the issue with OS not detecting the audio device, we can uninstall all audio drivers and perform a clean install. Uninstalling and reinstalling will replace all driver files, including any corrupted files that were causing the issue.Update Windows
Microsoft is constantly fixing bugs and problems in their Operating System by constantly providing Windows updates. So, if we have not updated the system and Windows stops detecting any component, it is ideal to Update Windows to the latest versions.
Here are the steps to update Windows.
Note: Installing Windows Update will also update all drivers to the latest version.Uninstall Windows Update
Although updating Windows to the latest version will solve most issues with it, there are cases where the Windows update itself consists of bugs and errors. Therefore, if the OS stops detecting the audio device after a Windows update, there is a good chance that some bugs in the Windows update are causing this issue.
If that’s the case for you, we can always uninstall recent updates. The following steps will guide you in uninstalling the latest Windows update.

DisplayPort is the new standard to transfer video signals from your PC and other sources to a monitor. With the better bandwidth and color accuracy of DisplayPort, most PCs have started providing the provision to use the DP cables and ports.
However, the use of DisplayPort is not without any faults. The most common issue while connecting the monitor using DisplayPort is the “No DP Signal From Your Device” Error. It means that the monitor is not able to receive video signals from the system while using the DP cable. And it can arise from a few hardware to configuration issues.
The causes for the monitor to show the “No DP Signal From Your Device” error even after it is connected through a DisplayPort interface are as follows:
Cable and Port Issues
Outdated or Corrupted Display Drivers
Incorrect Monitor Settings
Before trying the fixes, you should ensure that the power supply to the system is sufficient. Sometimes, a low voltage supply can prevent the system from booting, causing the monitor to not receive any input signals. You can use a voltage stabilizer or surge protector to run your devices.
If it still shows no signal, let’s move on to solving the issue.
If your monitor is set to receive signals from another source or a different port, then you will see the “No DP Signal” error.
So, you should choose the right source which you want your monitor to display from.
Keep the system and monitor turned on with the DisplayPort connecting them.
Find a menu button on the side or back of the monitor and press it.
Look for a Source or Input menu and select it.
Save the settings.
You should find the content on your screen.
Sometimes the graphics card malfunctions in the middle due to heavy computational load or other issues. As a result, the system could shut down the graphics driver causing the mentioned issue.
In such a case, you can simply press Win + Shift + Ctrl + B to restart the graphics driver. See if the display shows any content through the DP.
Furthermore, it is also possible that the system as a whole may have been faulty due to an unstable power supply or any improper power management setting.
Thus, you should try restarting the PC properly.
First, remove the power cable and other peripherals from the system.
Disconnect the DisplayPort cable and power adapter from the monitor.
Press the power button of the monitor for around 10 seconds.
Keep the setup without connecting anything for a while.
Insert all the cables and turn on the system.
The issue should be resolved now.
The majority of the time, the failure of the DP connection from the system to the monitor is mostly due to faults in cables and the ports. So, let’s move on to resolving the problem by inspecting the ports and cables.
Insert the DisplayPort connector into another port on your monitor properly.
Inspect if the system works by connecting the DisplayPort to another slot on your system.
See whether the cable is connected to the GPU’s DP in the system and not on the motherboard port. Computers with dedicated GPUs may not show any display if the monitor cables do not go through them.
Use the cable on another working PC and see if the contents are displayed on the screen.
You can also use a new DP cable to examine the occurrence of the problem again.
If there is still no signal, then the DisplayPort cable or the ports may be damaged. You should consult a service point to have it repaired.
If you are facing the problem of no DP signal in the external monitor that connects through the DisplayPort, it can be the issue of monitor drivers.
However, before repairing the drivers, you should check if the setting for projecting content to the second monitor is chosen correctly. Press Windows + ‘P’ on your primary monitor and choose Duplicate, Extend, or Second screen only for the project setting. See if the monitor shows the display in any of these settings now.
But, if the problem still persists, you will have to update the monitor drivers.
Press Windows + ‘X’ and select Device Manager from the list.
Similarly, find Display Adapters and update the drivers for the graphics card as well.
See if the issue is resolved now.
As the error is specific to DisplayPort, you can try using other means of transferring video signals, such as VGA, HDMI, DVI, etc.
However, there are cases when the issue is resolved by using the HDMI cable first and then switching to the DisplayPort cable later. This usually helps when you receive the No DP Signal error after the system wakes after the sleep state. The idea is to start the PC using an HDMI cable and then insert the DP to drive the monitor.
Remove the power cable from the system and monitor.
Disconnect the DP cable.
Choose HDMI as the source for the monitor display.
When the content is seen clearly on the screen, connect the DisplayPort connector to the PC.
Remove the HDMI cable and let the DP cable be connected.
The error should be gone now.
Whether you’re trying to set up multiple monitors or use an external display for your laptop, the “No HDMI signal” error might pop up. This message could indicate issues with either of your devices (source or destination).
You could also experience it due to incorrect source/projection settings, outdated drivers/firmware, or damaged components. But before diving into the related fixes, we recommend checking the loose connections first and try replugging the HDMI cable.
Adjusting the correct input source is an important thing to consider. If you’ve plugged in your HDMI cable to one port and set the input source to another, your monitor won’t display anything or will likely throw the “No HDMI Signal” error. Here’s a quick workaround to this problem:
Next, find the Input Source option and expand it, as demonstrated below.
If you get the “No HDMI signal” error after connecting your laptop to an external monitor, there may be an issue with the projection setting.
There are four different options available – PC Screen Only, Duplicate, Extend, and Secondary Screen Only. While the latter three options will cast your laptop content, the first one will not send an HDMI signal to the external display. Here’s a simple guide to changing the projection setting to fix this problem:
Sometimes, the bugs and glitches within your monitor could interfere with the HDMI signals. In such a scenario, performing a power cycle (turning the monitor on and off) will reset the configuration parameters, which might fix the error.
Here’s how you can do this the right way:
Firstly, turn off the monitor using the power button.
Wait for at least two to five minutes before you plug in the power cord.
Now, connect the HDMI cable and check if you still get the “No HDMI signal” error.
Damaged ports and cables could be the other reason you’re facing a signal problem on your device. To identify whether HDMI is working or not, check for bent/broken ports and cables.
You may even plug in another HDMI device on the port to identify if it has some sort of issue. Likewise, you can try a spare cable to find out if the former one was faulty. If you encounter any problems with the HDMI cable, kindly replace it with a new one.
Well, you may even get a Syncwire HDMI cable for better durability and flawless transmission. Thanks to its metal construction, the cable won’t get damaged even after being bent over 3000 times.
Another method to solve the “No HDMI signal” is to check the issue on another working monitor. This is to identify whether any components of your display device are damaged.
If you do not get any signal, know that there are problems with your PC, cables, and ports. However, if the desired content is displayed on the screen, it’s a clear sign to troubleshoot your monitor or you might even need to replace it!
The display adapters are responsible for sending display images to the monitor or related devices. Any issues with its drivers can directly affect the signals despite the type of monitor connection you’re using.
Likewise, only one display in a multi-monitor setup may show the “No HDMI signal” error. This is probably due to an outdated or corrupted monitor driver.
Lastly, restart your computer. Now, the monitor should detect the HDMI signal.
If the memory module hasn’t been installed properly, your device simply won’t boot. So, there’s a maximum chance that your output device won’t display anything or throw a signal error.
In this case, we recommend reseating the RAM sticks and cleaning the slots well. This ensures no debris or dust is stuck while the memory module is seated. Below is a simple guide that should help you clean and reseat the RAM:
First of all, properly shut down your computer.
Then, unplug all the connectors.
Push the two clips in opposite direction and remove the memory module from its dedicated slot.
Now, clean the slot and the RAM stick using a brush and compressed air.
Finally, turn on the computer and reconnect the HDMI cable. This time, you shouldn’t get the “No HDMI signal” error on your monitor.
Firstly, connect your monitor to a working laptop.
Download and install the required firmware and this should do the trick.
The final option is to perform a factory reset to restore the monitor to its original configuration. This will fix any bugs or glitches that might have interrupted the HDMI signal. For demonstration, we have used the MSI Optix G241V E2 model. But the steps should be similar on other monitors too:
Press the OSD button located on the rear side of the monitor.
Then, navigate to the Settings section.
Select the Reset option.

The audio service on your computer can sometimes stop working due to an outdated device driver, hardware malfunctioning, or a corrupt service file.
When I first upgraded to Windows 10, it stopped all of my audio devices from working, and I ended up having to reset my entire computer to restore sound.
However, there are a variety of more straightforward fixes that you might be able to make work before taking such drastic measures.
The Windows Audio Service is a Windows function that keeps your audio devices running. If it isn’t working, then no sound will emerge from your speakers. Though you can adjust whether the service is on or off in the Services area, that doesn’t always work if the service is broken or damaged for some reason.
The Windows Audio Service is supposed to start automatically when the computer starts. However, on some computers, it fails to do so and won’t necessarily start even when you change your settings.
Firstly, it’s best to make sure you’ve checked the basic aspects.
Normally, Windows might fail to start all drivers and services at startup. In this case, your audio service might not start or function properly as well. You can follow these steps to start all services when Windows is starting up.
A System File Checker scan helps find any issues in your Windows installation. Once it locates problems, it also corrects them without extensive input from you. It’s an excellent service to use when you experience issues with services, drivers, or other Windows essential functions.
Here’s how you can run an SFC scan.
The scan can take a while. It’s best not to do much on your computer while waiting for it to complete. Don’t start any new programs or run any other troubleshooters. Once it’s done, follow any prompts it gives you to correct system errors.
Similar to other components in your computer, Windows Audio service depends on additional services to run smoothly. These services are Remote Procedure Call (RPC), RPC Endpoint Mapper, DCOM Server Process Launcher, and Windows Audio Endpoint Builder. When such services aren’t working properly, Windows Audio might not respond as well.
Before restarting Windows Audio, we’ll need to restart these services. To view these Dependencies services, you can follow these steps.
We can see the services Windows Audio depends on the Dependencies tab. We will ensure these services are running before turning our attention to Windows Audio.
Repeat the above steps for the following services.
DCOM Server Process Launcher.
Audio Endpoint Builder
When Windows audio is not running, it means the audio software of your PC can’t communicate with the sound card. Starting Windows Audio will re-establish communication between your computer’s audio card and the software for proper functioning.
Occasionally, your computer’s sound might not be running on the appropriate system. To set the Windows Audio on the proper system, follow these steps.
Sometimes the audio services can malfunction because of an outdated device driver. The audio driver update can fix your computer’s sound not running correctly. The steps below will help you update your device’s sound drivers.
Automatically search for an update online or manually install a downloaded driver.
If the update doesn’t resolve, consider rolling the device driver back to the previously installed driver.
In rare cases, you’d have to uninstall the device and reinstall it for it to work perfectly.
If the button is grayed out and inaccessible, it means that an older driver isn’t available on your computer. In that case, you have to find the older version – likely on the manufacturer’s website – and install it manually. Once you’re done, restart the computer to see whether it worked.
This trick sometimes fixes Audio Service problems with Windows. However, if it doesn’t work, you’ll want to go back and change the settings to what they were before you started. Make a note of what your services are set to before beginning the process.
This process must be done on the administrator account for the computer. You won’t complete it if you aren’t on that account.
If you still haven’t been able to get the Audio Service to start, you might need to repair Windows. The Audio Service will try to start multiple times if it crashes but will stop at a certain point once it realizes that it isn’t starting successfully.
If you’re managing to get it to start, it might still be stopping simply because of an error in Windows.
Windows will do the Startup Repair process, and all you have to do is wait. Don’t try to do anything else on the computer. Don’t force it to shut down or restart if it seems to hang. The process can take a while.
If none of the above solutions work, it’s time to update your Operating System. It will also update your Audio Service when Windows installs the latest update.
But, make sure to back everything up before updating Windows. You can reset your PC from the Advanced Startup Options menu you used above to repair Windows.
However, it might be best to wipe the disk on which you’ll install the operating system. Once it’s wiped, use installation media like a CD or USB to install Windows again.
Your computer audio gives you the Error message “Audio Service Error 1068” or “Audio Endpoint builder error 126.” After troubleshooting your computer’s sound, nothing seems to work. The following methods might work for you.
Press Win Key + R open run.
Scroll through the Services and start Audio Service and Audio Endpoint Builder Service.
Restart your PC.
Windows audio service access denied means you don’t have permission to use the Service. It can occur after a recent Windows update. The following methods can help you resolve the issue at hand.
After going through the above steps, try to restart the Service. Don’t close the service window after completing the above steps. The following procedure is crucial for troubleshooting the problem.
Repeat the same process for your administrator account. Restart the services and restart your computer.
You can fix this error from the command prompt:
If the above procedure fails, try the following.
There could be a time when none of these fixes work. In such distress, try this final remedy.
There isn’t a way to directly reinstall the service. You can restart or disable it in the Services menu, but it’s part of Windows and not something to install on its own. You can restore, repair, or reinstall Windows if you think the application itself is corrupted or damaged.
