I don't used audio much, so I just noticed it and have no idea when it actually stopped working - but now I need audio.
All are set to use PulseAudio.
It does not matter what the guest OS type is.
Virtualbox 6.1.26 installed (from http://download.virtualbox.org/virtualb ... _amd64.run) on an x86_64 Slackware (current) using kernel 5.14.3.
Needless to say all other applications are using PulseAudio just fine, sound is OK.
When I start up a VM configured for PulseAudio I can see in the system messages this:
Code: Select all

Sep 22 03:19:34 darkstar-1 pulseaudio[26678]: [pulseaudio] main.c: Daemon startup failed.

00:00:00.970630 HDA: Codec reset
00:00:00.970636 HDA: Reset
All fixes suggested there are not needed, are already in place.
Does anyone know what else should I check to figure out what is wrong?
