There are several ways you can do that, including by uninstalling the device, using an Automatic Driver Update Utility, and troubleshooting audio problems with Nvidia High Definition Audio Driver. If you’re experiencing audio problems with your computer, you may want to troubleshoot the driver that’s causing them. How to Fix Audio Problems With Nvidia High Definition Audio Driver Windows 11?

Most solutions found on the web being quite old, I wanted to know if there is now an ultimate solution or a known driver version which solves all known nvidia HD audio problems? Could this be a side effect of the registry edit? Otherwise, is there a way to find out what is happening?

To solve this, I have to stop and restart the application running the movie (be it media player, VLC, a browser, it occurs with various applications.) - it happens randomly, maybe one out of 20 times I start a movie? And it is not a problem of starting the movie after the computer has been idle for a while. Notably, I applied the registry edit to disable idle power state which seems to have fixed the issue of 5.1 reverting to stereo:īut now it can happen that when starting a movie, no sound is output via HDMI at all. Each workaround seems to fix something but either not fix everything or add another problem.

So I have been plagued by various nvidia HD audio driver issues (silent stream bug, intermittently no sound, sound setup reverting from 5.1 to stereo, etc.), with audio being output to hdmi together with video.
