This post describes why audiodg.exe is using high CPU on Vista and later systems. If you haven’t seen this yet, you’re probably wonder why an audio executable is using so much processing power.

Once you fix the issue, you’ll be back to playing those videos smoothly again.

Audiodg.exe is Windows Audio Device Graph Isolation. Sometimes audio effects through this service can consume CPU and memory if not properly coded. Since this process runs the sound driver independently of the user profile, it makes it difficult to kill the process.

Troubleshooting Audiodg.exe Using High CPU Procedure

First things first. Update your sound drivers. If you’re running laptops, here’s a post I did that went over the Laptop Driver Websites. If that doesn’t do it, update the media player or application that’s experiencing the undesired result.

If the issue still persists, try the following:

  1. Right click speaker icon in the notification area
  2. Select Playback Devices
  3. Double click the default device (green check mark)
  4. Click Enhancements tab
  5. Uncheck undesired enhancements or tick Disable all enhancements check box
  6. Click OK button
  7. Close window
  8. Click OK

Now your video files should play back a little smoother. Furthermore, your PC will be snappier and produce less heat.


I’ve seen this process work pretty consistently across the board. I even found a question regarding audiodg.exe using high CPU in Microsoft’s Answers site.

If this didn’t work for you, what did you try to get it to work?
