I can confirm this bug on my Dell Dimension 1100, running Intrepid with
latest updates as of 23/7.
With the snd_pcsp set to index "-2" (default): ALSA applications work
with the proper sound card - you can verify via GDM's starting drumbeat
upon login, or using a sound application that does not use PulseAudio.
PulseAudio still chooses snd_pcsp as the primary PCM device, however
(will attach verbose PulseAudio log).
In essence: the problem is not only with the snd_pcsp module index, but
PulseAudio's incorrect selection of the appropriate PCM device (it
appears to ignore the ALSA module index).
Workaround: a) blacklist snd_pcsp to eliminate the problem; or, b) use
"padevchooser" to select the proper ALSA sink for your sound card (full
name available from the PulseAudio Manager).
Real fix: Configure/patch PulseAudio to honour ALSA module indexes, or
to completely ignore the PC Speaker kernel module?
