Suggested January 2024 How To Fix Audio Service Not Running
The audio service on your computer can sometimes stop working due to an outdated device driver, hardware malfunctioning, or a corrupt service file.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.

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.
If you’re unsatisfied with the quiet, tinny sound coming from your TV’s speakers, a soundbar can seriously improve your movie-watching experience. But while most soundbars are space-efficient and easy to hook up, they still have an occasional quirk or two—most notably an audio delay that causes audio and video to be out of sync with the mouths moving on screen. We’ll walk you through how to fix the audio delay in your soundbar.How your TV and soundbar get out of sync
I’ve tried and reviewed countless TVs and the best soundbars, and audio delay is an extremely common issue. Many people jump to blame a certain brand or model of soundbar, but it’s not always that simple. Frequently, this delay is inherent to how TVs and soundbars decode audio.
“It is a complicated problem,” explains Allan Devantier, vice president of audio research and development at Samsung. “You’ve got all these different formats for audio, so there’s a large amount of number-crunching the TV has to do to unpack it all.”
Specifically, when you watch a Blu-ray or stream a movie on Netflix, that audio is encoded in a certain format—like DTS or Dolby Digital. When that signal is sent to your TV or soundbar, the device has to decode the audio in order to play it over your speakers, and that process takes time. We’re talking milliseconds, usually, but time nonetheless—and higher bitrate formats (like multi-channel Dolby Atmos) might take longer than a low-bitrate stereo track, leading to a more noticeable delay.
If you’re playing that audio on your TV’s speakers, your TV is doing all the unpacking, so it can hold off on sending both the video and audio until the process has finished. But when you introduce another product—like a soundbar—your TV might decode the video while your soundbar decodes the audio. If the TV doesn’t know exactly how long your soundbar will take, it may send the video before the soundbar has finished, leading to a disastrous mismatch of the mouths on screen. Couple that with any other processing you’re doing—like motion smoothing on your TV, or “virtual surround”-type features on the soundbar—and you’re basically guaranteed out-of-sync dialogue. Manufacturers try to fix this audio delay problem on their own, but there’s only so much they can do.
“We analyze all the different variations of streams that can come in, and calculate a best guess of how we should delay the audio and video to keep it synced,” says Devantier. “But it can only be an estimate.” He also tells me their calculations assume a Samsung soundbar, so you may notice more of a delay if you use products that weren’t designed to work together.
All hope is not lost, though. There are a few things you can do to combat this challenge, even if you don’t have brand-matched gear. After hours of testing with countless soundbars for TV over the years, here are a few ways on how to sync audio and video that I’ve found.Adjust the audio delay on your TV or soundbar
Let’s start with the obvious: many TVs and soundbars have a built-in “audio delay” or “lip sync” setting that aims to play the two in tandem. You’ll find this in the audio settings of your TV and/or soundbar, and if you’re lucky, adjusting it a few notches may fix the problem.
Unfortunately, many TVs and soundbars only allow you to adjust it in one direction: delaying the audio. But if your audio and video are out of sync because the audio is behind the video—i.e. already delayed—delaying it further obviously won’t help. Ideally, your TV or soundbar would offer a negative delay, sending the audio a few milliseconds earlier (or the video a few milliseconds later). Many devices I’ve tested—including the LG TV, Vizio TV, Vizio soundbar, and Samsung TV I own—do not allow adjustment in both directions, which makes the feature all but useless against audio delay. To their credit, though, Devantier tells me Samsung has done a lot of work on this problem over the past few years, and 2023 models now have the ability to adjust its delay in both directions—though I haven’t yet tested its efficacy myself.
If you’re lucky, your streaming box or Blu-ray player might have its own audio adjustment feature. This is less common, in my experience, but it’s worth a shot. If none of these lip sync features solve the problem, though, you’ll have to get a bit more creative to fix the audio delay.Turn off audio and video processing
Dig through your TV and soundbar’s settings for any features that alter the video and audio in some way. In particular, look through your soundbar’s menu for equalizer settings, presets like “movie” and “sports” mode, dialogue enhancers and volume levelers, or features like “virtual 3D” surround sound. Turn them all off, and you should find the delay is much smaller, if not eliminated. All those features require processing on the part of your device, which takes a few milliseconds of time.Change the audio format on your TV
In my experience, this lip sync problem is most common when sending audio from your TV to your soundbar using HDMI ARC or optical out. Your TV sends the audio to the soundbar, the soundbar takes a moment to unpack the signal, and sends it out after the corresponding video has reached your eyeballs.
However, your TV may be able to do this audio unpacking process itself—taking the load off your soundbar and allowing the two to stay in sync. In your TV’s audio settings, see if you can change the audio format to PCM instead of Dolby Digital, bitstream, or passthrough. I’ve found this fixed the audio delay on all my TVs.
However, this does come with its own downsides. Some TVs can’t decode certain formats, like DTS or Dolby Atmos, which means this trick won’t work on movies encoded in those containers. It also could mean you lose multichannel audio—if your soundbar only contains two speakers, that’s fine, but if you have a 3.1 or 5.1 soundbar, you’ll lose your surround sound, which makes this solution a non-starter.

The best solution, in my opinion, is to re-configure how your soundbar and TV are connected. If your Roku is connected to your TV, which then sends audio to your soundbar over HDMI ARC or optical, you’ll have to use the above (often imperfect) solutions to mitigate the delay. But if you plug your Roku into the soundbar, then pass video through the soundbar to the TV via HDMI cable, any delay caused by audio processing will disappear—because your soundbar will wait to send the video to the TV until all its work is done unpacking the audio. (This may introduce a video delay instead, if your TV is doing its own processing, like motion smoothing, but you can use the lip-sync feature on your soundbar to delay the audio to match.)
Despite being the ideal audio delay fix, I mention this last because it comes with one big downside: most soundbars don’t have many inputs. In fact, most affordable soundbars only have one HDMI In port, which means if you have a Roku, a Blu-ray player, and a game console, you won’t be able to plug them all into the soundbar at the same time (unless you use an HDMI switcher, which just introduces more wires and complexity). It also doesn’t work if you use your TV’s smart apps to watch Netflix, or if you watch local channels on an antenna plugged into your TV—in those circumstances, there’s no external box to plug into the soundbar, so you’re forced to route audio to the soundbar over delay-inducing HDMI ARC or optical.
You can see how such a simple thing gets complicated quickly. If you’re lucky, your TV or soundbar will be one that allows the lip sync feature to adjust in both directions—or at least you’ll have a higher-end soundbar with enough inputs for all your devices. If not, you’ll have to play around with the above tweaks to get things close enough.
