Public bug reported:
Sound playback is unstable on my Ubuntu 16.04.1 LTS running on Virtual
Box (host machine iMac MK462).
The easiest way to reproduce (at least for me): start Firefox, play
something on Youtube, close Firefox, restart Firefox, no sound for
videos (or VLC player or aplay).
Killing /usr/bin/pulseaudio fixes the issue until something is started
and restarted again.
grep -i pulseaudio /var/log/syslog contains following lines

timer-based scheduling because running inside a VM.

the message bus security policy blocked the reply, the reply timeout expired,
or the network connection was broken.

write.
Sep 1 16:38:53 jasu pulseaudio[4574]: [alsa-sink-Intel ICH] alsa-sink.c: Most
likely this is a bug in the ALSA driver 'snd_intel8x0'. Please report this
issue to the ALSA developers.
Sep 1 16:38:53 jasu pulseaudio[4574]: [alsa-sink-Intel ICH] alsa-sink.c: We
were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned
0 or another value < min_avail.
