[Asus GX531GX] Internal speakers are sometimes noisy - distorted audio
I have an Asus Zephyrus S GX531GX laptop and a pair of Asus Delta USB headphones. This system can dual boot Ubuntu 20.04 and Windows 10. Sometimes the audio is distorted. Listen to attached example files.
It's almost like a turntable loses power and the playback slows down and stops.

There is no problem here.
Distorted audio here.
Steps to reproduce
I don't have a 100% way to reproduce this problem. But I think it happens more often when the USB headphones are plugged in and I stop using Windows and reboot to Ubuntu.
What is the current bug behavior?
What is the expected correct behavior?
