VirtualBox 6.1.28 and PulseAudio problem

[3eka]

Hi all,

I have updated virtual box:

:; pkg list virtualbox
NAME (PUBLISHER)                                  VERSION                    IFO
system/virtualbox                                 6.1.28-2020.0.1.0          i--

and, after that, my Ubuntu guest failed to start, with error:

...

Guest have had audio enabled and it was set to pulseaudio. Changing that to OSS audio makes it boot. BTW, pulseaudio is running on host:

:; ps -Z -ef | grep pulse[a]udio
  global predrag*  9946     1   0   Nov 17 ?           0:56 /usr/bin/pulseaudio --start --log-target=syslog

It was working in previous (I think 6.1.22 version).
Regards.
