Cpu Constantly at Max Clock Speed and Audio Bug

Jam13Roll · September 28, 2021

I recently upgraded from a GTX710 to an RX6600XT. Since then, my cpu has constantly been running at max clock speed, even when task manager is the only application open. I have made sure that xmp profile is enabled and that I am using the power saving plan, however nothing is having any effect on this. I am using a Ryzen 7 5800X if that is of any importance. If I disable core performance boost in the bios, it runs at 99% instead of 100%.

Another problem I have been running into is my audio. Since the upgrade, I have not been able to use my monitor (allbeit an old one) as an audio output device and it has instead been replaced with ‘2-24_LCD_TV (AMD High Definition Audio Device’, which I am not able to move the audio slider on. Troubleshooting the problem just confuses me (included picture of the result).

I have also performed an sfc /scannow, in which corrupted files were found and fixed, however that did not solve any of my issues.

If anyone is able to help me with any of these problems, it would be greatly appreciated!

Update: The audio problem has been fixed! I will leave a link to the website that I used in case anybody is experiencing the same issue: https://www.driversupport.com/knowledge-article/no-audio-output-device-is-installed-error-windows-10/

However, the main problem of the maxed cpu clock is still ongoing. Any help related to that would be amazing!! (Thanks for your suggestions so far!)

Start by posting a screenshot of the task manager Processes tab sorted by CPU usage so people can see what's actually hogging the CPU.

Then use DDU in safe mode to completely wipe both Nvidia and AMD graphics drivers, and do a clean install of the AMD drivers since the audio thing looks a lot like a driver conflict.

Just posted the task manager photo. I have done two ddu wipes, one for the old card and one for the new while I was trying to fix the audio. I have even done a factory reset (wiping all files as well), however the problem remains. I will do another ddu wipe, but I don’t know whether it will actually do anything.
