Jan 13, 2019 Windows Driver Developer uses Windows Audio Device Graph Isolation to insert their Audio effect to enhance the sound quality. For example, HP use Beats audio and Dell uses WAVE MAXX audio. Notwithstanding many Windows users have to face the windows audio device graph isolation. In order to make sure you don’t have a virus on your hands, right-click the “Windows Audio Device Graph Isolation” process and click “Open file location.” A folder will open. Check the file path for the folder. If it’s in System32, there’s a good chance it’s not a virus.
- This happens very often; where I will be surfing the web/talking with friends/playing games and suddenly my audio goes out. I have to end a task called 'Windows Audio Device Graph Isolation' and then end and rejoin the Skype call to get it to work again.
- Audio Device Graph Isolation is eating ram in Windows 10. The end result is that the PC begins to stutter from the lack of available memory to do things. From other posts, I've tried reinstalling the audio driver, checking for an enhancements tab (I don't have one with Beats Audio) and disabling exclusive mode.
If you spend any time in Task Manager, you may have noticed something called “Windows Audio Device Graph Isolation”, and wondered why it sometimes goes a bit nuts with system resource usage. Here’s what it does and what you can do if that happens.
RELATED:What Is This Process and Why Is It Running on My PC?
This article is part of our ongoing series explaining various processes found in Task Manager, like Runtime Broker, svchost.exe, dwm.exe, ctfmon.exe, rundll32.exe, Adobe_Updater.exe, and many others. Don’t know what those services are? Better start reading!
What Is the “Windows Audio Device Graph Isolation” Process?
Sporting an awesome-sounding name that doesn’t really tell you anything, “Windows Audio Device Graph Isolation” is an official part of Windows. The process serves as the primary audio engine in Windows 10. It handles digital signal processing, including the advanced audio enhancement effects provided by Windows.
“Windows Audio Device Graph Isolation” is separated from the standard Windows Audio service. Isolating the services like this allows developers of hardware audio products include their own audio enhancement service without having to replace the Windows Audio service itself. This, in turn, leads to better stability. Windows Audio is so deeply hooked into Windows that a crash is often likely to take down the whole system rather than just your sound. By isolating the digital signal processing–the part more likely to experience a crash–to a separate service, crashes are more contained.
This type of isolation also ensures that Windows always provides you a way to turn off audio enhancements in the OS, regardless of what type of hardware you’re using. For whatever reason, audio hardware manufacturers very often don’t give you that option themselves.
You should also note that with some audio hardware, manufacturers may actually replace the “Windows Audio Device Graph Isolation” with their own digital signal processing service. Here’s a look at the service used by a Creative SoundBlaster Recon3D.

Of course, if you don’t have “Windows Audio Device Graph Isolation” running on your system, you won’t have much need to troubleshoot it!
Why Does It Sometimes Consume So Many System Resources?
Unfortunately, poorly written audio enhancement drivers can cause more than just the occasional crash. Some people have trouble with enhancements causing significantly higher use of system resources, consuming your CPU or memory or even thrashing your hard drive. Under normal conditions, you should see “Windows Audio Device Graph Isolation” using 0% of your CPU, minimal memory, and no disk activity. These numbers may spike when audio effects are being applied, but not much and they should return to the baseline quickly. If you see “Windows Audio Device Graph Isolation” routinely using more of any of these three resources, then you may have a problem.
The good news is that it’s likely easy to resolve since part of the reason for isolating this type of processing is giving you an easy way to turn it off. You can certainly try whatever software your hardware manufacturer supplies and see if you can disable some of the advanced audio effects. You can also do it right in Windows for devices that support it. Open up the Sound properties dialog by right-clicking the speaker icon in your Notification area and then clicking “Sound.” You can also open up your Control Panel and run the Sound applet there. Same thing.
On the “Playback” tab of the “Sound” window, select the device that you suspect may be causing issues and then click “Properties.”
On the “Enhancements” tab of the device’s Properties dialog, you’ll see a list of enhancements supported by the device. What you see depends entirely on the device you’re using. Here, we’re looking at a webcam/microphone that’s built into a monitor. We’d suggest you start by just selecting the “Disable all enhancements” option and see if that resolves your problem.
If disabling all the enhancements does fix the problem, then you know you’re on the right track and you can go back and try disabling each specific enhancement in turn to narrow down the cause. If disabling all the enhancements for a device doesn’t solve your problem, then you should re-enable them and move on to test another device.
Can I Disable It?
You can’t really disable “Windows Audio Device Graph Isolation” without also disabling the main Windows Audio service as well, and disabling them wouldn’t buy you much except for no sound on your system. You can’t even temporarily end the task. If you try, Windows will pop up a notification asking if you’d like to open the Audio Troubleshooter instead.
And the truth is, running through the troubleshooter couldn’t hurt. It’s unlikely to solve your problem if you’ve already tried disabling enhancements, but you never know. You can also get to the troubleshooters by hitting Start, typing “troubleshooting,” and then hitting Enter.
Could This Process Be a Virus?
“Windows Audio Device Graph Isolation” itself is an official Windows component and very likely not a virus. While we haven’t seen reports of any viruses hijacking this process, it is always possible we’ll see one in the future. If you’d like to be sure, you can check out the process’ underlying file location. In Task Manager, right-click “Windows Audio Device Graph Isolation” and choose the “Open File Location” option.
If the file is stored in your WindowsSystem32 folder, then you can be fairly certain you are not dealing with a virus.

That said, if you still want a little more peace of mind–or if you see that file stored anywhere other than the System32 folder–scan for viruses using your preferred virus scanner. Better safe than sorry!

When diagnosing high CPU or disk usage, the Task Manager in Windows is a user’s best friend. Giving real-time statistics on what processes are using which resources, you can identify a “rogue” process easily. Once you know what’s doing the damage, you can better remedy the issue and save your computer from being fried by its own processes.
You might notice a process that can spike to, or stay constantly at, a high CPU usage value. It’s called “Windows Audio Device Graph Isolation,” and it’s a problem a few users have faced. The question is what it means. This somewhat cryptic process name doesn’t do you any favors for tackling the issue and bringing your CPU usage down to a more reasonable level.
If you’re having problems with this strange process, let’s explore what it is, and more importantly, how to stop it from using your valuable resources.
What Is “Windows Audio Device Graph Isolation”?
Sounds very cryptic, doesn’t it? From the name alone you can derive that it’s something to do with the computer’s audio. Past that, however, it’s hard to tell what exactly this process does.
This process is mostly aimed towards developers creating drivers that can interact with the computer’s sound and to additional effects. Because this will affect all sounds coming from the computer, they have to talk to Window’s audio service.
To aid with this, Microsoft isolated a part of their audio service into a separate process which is Windows Audio Device Graph Isolation. Having a separate service from Window’s core process means that a crashing third-party audio driver won’t take out the entire operating system with it. It also supplies tools to aid with DRM.
Which will allow AltSoftSerial to be used together with other libraries which require the timer which AltSoftSerial uses by default.– Can be sensitive to interrupt usage by other libraries,but not as sensitive as SoftwareSerial due to the short time interrupt latency.– Still doesn’t support signal inversion like the SoftwareSerial library. EXAMPLE CODEThis is a modified internet example code using AltSoftSerial on baud rate 57600, upload the code after setting the baud rate and hit Arduino’s Reset button.But now you don’t have to switch the UART switch to the communication mode anymore (as you already using another serial port for communication) just leave it at the SWS which stands for Software Serial and watch your application working 😉Hope the feature help you out guys, if you have any questions please feel free to leave it in the comments 🙂. The newer version of 1Sheeld (1Sheeld+) built to support both iOS and Android devices,but not just that! Arduino software serial. CONS– Limited to certain pins (supported by 16-bit timers) as pins 8,9 & 10 in arduino UNO.– Affects libraries uses the same 16-bit timers which will off course disable some PWM pins.while if the board has several 16-bit timers you can configure which timer AltSoftSerial uses by editing “config/knownboards.h” within the library.
Fixing the Issues
So now that we know what the process does, we can apply what we learnt to fix it should it go out of control.
Disabling Sound Effects
Windows Audio Device Graph Isolation was created to handle additional sound enhancements on your PC. Therefore, if we disable the PC’s ability to play sound enhancements, this might solve the problem. This is especially useful if you have zero desire to use sound enhancements on your PC. Note that this isn’t the same as disabling the computer’s sound! It’s just disabling the ability to add fancy effects to it (such as an echo).
To disable all sound enhancements, first right-click the speaker symbol in your tray, then click Playback Devices.
You’ll see a list of different ways your computer can output sound. Find the default device your PC uses to output sound. You can tell which this is because it’s labelled as “Default Device,” and the green bar to the right will light up as you play sounds on your PC.
Adobe shockwave update cnet. Right-click this and click “Properties” or click on it and click the “Properties” button below.
In the window that pops up, go to the “Enhancements” tab.
You’ll see a list of sound effects you can apply to your sound. Of course, we’re not here to use these; we’re here to turn them off! At the top you should see an option to disable all sound effects. Check this and OK out of all windows.
This tells Windows you don’t want any additional sound effects, which should put a little less strain on the audio device graph isolation process.
Reinstall Audio Drivers
Windows Audio Graph Isolation Windows 10 Free
If this doesn’t do the job, the problem may not be with the sound effects. Instead, it might be with the audio driver that handles these effects.
To solve this, first download the current version of your audio drivers. You can do this from your PC manufacturer’s site, or you can find the model of your motherboard and search for audio drivers associated with it.
Once done, you can either install these straight away and see if it solves the problem or do a “clean sweep” of the drivers to ensure nothing from the old driver installs interferes.
To do a fresh install, we need the Device Manager. Press “Windows Key + R” and type
devmgmt.msc
into the Run window that appears, then click OK.Expand “Sound, video and game controllers,” right-click your audio driver, and click Uninstall.
In the popup that appears, check the box that asks if you want to delete your drivers and click OK.
Restart the PC. Windows will likely install audio drivers for you, but if you want to be absolutely sure you’re installing the best drivers for your PC, you can manually install them with the drivers you downloaded earlier.
Check for a Virus
If neither of the above options work, it might be a case of a virus disguising itself as the Windows Audio Device Graph Isolation process to perform its nasty deeds. In order to make sure you don’t have a virus on your hands, right-click the “Windows Audio Device Graph Isolation” process and click “Open file location.”
A folder will open. Check the file path for the folder. If it’s in System32, there’s a good chance it’s not a virus.
If it’s anywhere else, or if you’re still suspicious that a virus could be the problem, perform a full virus scan with your trusted antivirus solution immediately.
Audio Woes
With such a cryptic name such as “Windows Audio Device Graph Isolation,” it’s hard to know how to troubleshoot problems with it. Now, however, you know what the process does, what areas of Windows it uses, and thus, how to control it should it go awry.
