Slight weirdness for me too. Probably the first time since I installed
6.0.5 I tried to play a youtube video and got no sound (HDMI via
rpmfusion nvidia driver).
I tried to reboot to go back one kernel version and see if sound worked
there, and the reboot blanked the screen, but then was stuck. I eventually
power cycled the computer and it came back up OK and sound did work on
the previous kernel.
At this point I rebooted (which worked) and went back to 6.0.5 and sound
was working fine again.
So something about a complete power down seems to have made it better.
