All
I have posted about this in the past, and I have done a fair amount of fiddling around with pulseaudio, alsa and other system files, do I have decided to do a clean / fresh install.
I have a Lenovo Legion 9 and I have noticed that when I boot the sound works after I login for about 60seconds, then it just stops working.
Here is some of my system info, thanks in advance for any help:
