Re: NVDA and Windows Audio Service (audiodg.exe)

Ralf Kefferpuetz


Have you tried to disable the audio enhancements, please read below.

In order to fix the high CPU usage, disable the audio enhancements processed by the audiodg.exe file. To disable the audio enhancements, try the following steps:

1. Right-click the speaker icon in the right-hand notification area on the taskbar.

2. Select Playback Devices from the menu. A list of devices should appear on the screen.

3. Double-click the device that has a green checkmark. The properties windows for that device should open.

4. Click the Enhancements tab at the top.

5. From the list of enhancements, uncheck all of them, or click the Disable all enhancements checkbox.

6. Click the OK button to save your changes and close the window.

7. Click OK to close the Playback Devices window.

Hi All

I’m having an alarming issue with NVDA eating all my ram through the Windows Audio Device Graph Isolation Process; audiodg.exe.

Quite a technical issue – I’ll

Try and explain it the best I can.

I had been using my laptop, running Windows 10 and NVDA 2018.1.1, for about 3 hours doing a lot of

Emails and document editing using Microsoft word; so not that advanced. Suddenly, I got a blue screen error telling me my virtual memory had been used up and my laptop needed to restart.

I was naturally curious as to what could’ve, first used so much ram, then that it needed to eat all my virtual memory up.

I consulted task manager and found that the windows audio device graph isolation process – file audiodg.exe was using just over a GB of ram! I new this wasn’t normal and as I was watching it was increasing very fast.

It only increases when NVDA is talking though, that’s the weird thing. I’ve verified that all my audio settings are normal and my audio drivers are up to date. There is nothing else I have running that comes close to using this much ram.

After a while the audiodg.exe program uses so much ram that it shifts some into virtual to try and free some ram. This process then continues until over 30 GB of virtual has been used; then I get the blue screen error.

I then tried using narrator to see what happened to the amount of ram audiodg.exe was using and it was a normal amount and wasn’t increasing. I then played some music and the results were fine again.

Has anyone had this issue before that could help me come to a solution on how to fix this weird leak. If there’s anymore info you need please let me know.
