Ok, I added --log-level=4 and rebooted.

The complete log (from boot until playing a stream on the muted device]
is available at: http://pastebin.com/V4N7ta0d

Maybe interesting is:

Okt 08 15:39:42 marduk pulseaudio[454]: could not open configuration
file /usr/share/alsa/ucm/Xonar STX/Xonar STX.conf
Okt 08 15:39:42 marduk pulseaudio[454]: error: could not parse
configuration for card Xonar STX
Okt 08 15:39:42 marduk pulseaudio[454]: error: failed to import Xonar
STX use case configuration -2
Okt 08 15:39:42 marduk pulseaudio[454]: UCM not available for card Xonar STX

Xonar STX is the card I want to use. When I saw this message the first
time, I deleted all files in pulse state directory /var/lib/pulse and
rebootet, but it still appears.


Is there maybe some race condition between kernel module loading for the
card (snd_virtuoso) and pulseaudio restore module?

Thanks,
