Public bug reported:
Binary package hint: pulseaudio
On systems where there are several sound cards available, pulseaudio
seems to choose arbitrary sound card (not default ALSA sound card).
My board has integrated ICH5 and SB Live PCI installed. ALSA is set to
use SB Live.
[EMAIL PROTECTED]:~$ cat .asoundrc.asoundconf
# ALSA library configuration file managed by asoundconf(1).
#
# MANUAL CHANGES TO THIS FILE WILL BE OVERWRITTEN!
#
# Manual changes to the ALSA library configuration should be implemented
# by editing the ~/.asoundrc file, not by editing this file.

I want to use sink 1 (my sound card, not the integrated ICH5). However,
there is no user interface to choose this anywhere. Preferences > Sounds
do not have option to choose PulseAudio sink. For some reason,
PulseAudio prefers ICH5. Thus, I cannot play any sounds (except by
changing my wiring and using ICH5 plug, but that's not what I want due
to suboptimal sound quality).
Workaround:
Edit /etc/pulse/default.pa
sudo pico /etc/pulse/default.pa
Add line:
set-default-sink alsa_output.pci_1102_2_sound_card_0_alsa_playback_0
(You can get available sinks with pulseaudio -C and list-sinks commands)
Restart PulseAudio:
sudo /etc/init.d/pulseaudio restart
