I can see a few issues in the log from your VM:
1. Buggy audio in the VM's kernel driver (says pulseaudio):
jul 05 11:05:21 VM-Xubuntu-2004 pulseaudio[1406]: ALSA woke us up to write new
data to the device, but there was actually nothing to write.
jul 05 11:05:21 VM-Xubuntu-2004 pulseaudio[1406]: Most likely this is a bug in
the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA
developers.
jul 05 11:05:21 VM-Xubuntu-2004 pulseaudio[1406]: We were woken up with POLLOUT
set -- however a subsequent snd_pcm_avail() returned 0 or another value <
min_avail.
jul 05 11:05:21 VM-Xubuntu-2004 pulseaudio[1406]: Disabling timer-based
scheduling because running inside a VM.
2. More problems with the VM's kernel driver:
jul 05 11:05:28 VM-Xubuntu-2004 pulseaudio[1406]: Unable to set sw params:
Permission denied
jul 05 11:05:28 VM-Xubuntu-2004 pulseaudio[1406]: Failed to set software
parameters: Permission denied
jul 05 11:05:28 VM-Xubuntu-2004 pulseaudio[1406]: Error opening PCM device
front:0: No such file or directory
jul 05 11:05:28 VM-Xubuntu-2004 systemd[1399]: pulseaudio.service: Succeeded.
3. A couple of kernel crashes apparently relating to running out of
memory in the VM.
So I suggest:
* Giving the VM more memory.
* Running fewer apps in the VM.
* Configuring the VM with a different type of virtual audio device (if you
can).
** Package changed: pulseaudio (Ubuntu) => linux (Ubuntu)
** Changed in: linux (Ubuntu)
Status: Incomplete => New

Title:
pulseaudio not working in Virtualbox
Status in linux package in Ubuntu:
New
Bug description:
I run my "work" VMs and in Xubuntu pulse audio often does not start.
In this dump I tried to start music through Firefox and through my
media player quodlibet and none of the audio starts.
See attachment with the pulseaudio volume control and quodlibet stuck
on time 0:00 like Firefox.
I do not have the problem with plain Ubuntu, Ubuntu Mate nor with
Ubuntu Studio.
The problem is annoying, because I use Xubuntu for office and
communication like Email and the WhatsApp/Firefox/ICE combination and
with this bug WhatsApp is useless.
