Connecting to pulseaudio in dom0 problem

[marmarek]

Sometimes there is no audio in newly started VM. Looks like problem with connecting to pulseaudio in dom0 by pacat-simple-vchan.

Some collected infos:
[root@dom0 ~]# tail /var/log/qubes/pacat.20.log
pacat-simple-vchan.c: pa_simple_new() failed: Connection refused

Same for every pulseaudio tools... But from old domains where pacat-simple-vchan is already running - audio is working.

[root@dom0 ~]# ls /tmp/pulse-*

Some dbus problem? I've suspected tmpwatch, but it is configured to
clean files 10d+ old and my system have only 8d uptime now.

Cannot reproduce. I still have raised loglevel of pulseaudio, so if it happens again will have more info.
Closing for now.
