Bug#671383: pulseaudio: module-udev-detect fails to find the soundcard (hence dummy output aka no sound)

Package: pulseaudio
Version: 1.1-3
Severity: important
Dear Maintainer,
Problem: out-of the box pulseaudio gives a "dummy output" in Kmix aka no sound
Diagnostics:
I think that there is a problem with the start-up execution of the module-udev-detect.
I cannot say if it is the timing when the module is executed, or the module itself.
Executing
pkill pulse ; sleep 10 ; pulseaudio -vvvv
gives back sound.
The manual fix below gives an apparently working pulseaudio, and explains why the problem concerns module-udev-detect.
This bug is related with
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=551498
up to you to decide if to merge or not.
Good luck
Ric
### (Dirty) manual fix ###
manually load the sound card that for me happens to be card 0 and disable theloading of module-udev-detect
~# diff _etc_pulse_default.pa_original /etc/pulse/default.pa
44,45c44,45
< #load-module module-alsa-sink
< #load-module module-alsa-source device=hw:1,0

> load-module module-alsa-sink
> load-module module-alsa-source device=hw:0

< load-module module-udev-detect
---
> #load-module module-udev-detect
The following to activate debugging output
~# diff _etc_pulse_daemon.conf_original /etc/pulse/daemon.conf

< ; log-target = auto
< ; log-level = notice

~#
Sound is back
