Windows 10: Sound not working/audiodg.exe crashing

Just last night, I was playing a game on my laptop while connected to a tv through an HDMI cord. This afternoon, the tv was off but my laptop was in standby. Display and audio were set to the tv only at the time. I unplugged the cord, and since then I've been having gpu usage issues and no audio comes from my laptop. I've tried updating drivers, the laptop itself, antivirus scans, nothing is working.

I can't seem to figure out what's wrong, and the built in troubleshooters can't find any issues.
Side note, I can plug the hdmi back in and get audio on the TV, but plugging in headphones or a speaker no longer works either

:)

 

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

 

Audiodg Issues

 

Audiodg Issues

Like many others, I've encountered the high CPU issue when audiodg (Windows Audio
Device Graph Isolation) is running. By ending this process in the task manager, I can use my PC without issues. However, after a recent Windows update, I cannot end the task under "Processes" anymore. I was able to end
process tree under "Details". Now, I cannot get any sound. The automatic troubleshooting cannot fix the problem. The problem statement is "Audio services are not responding" although Windows Audio service and Windows Audio Endpoint Builder
are running.

Probably, the problem is due to permanent termination of audiodg. In the past, even though I ended the process, it would show up again as needed. I cannot get audiodg to run anymore even if I run it as Administrator. Does anyone know how to get audiodg
to run?

Thanks in advance!
