Description Joachim Frieben 2008-08-19 05:02:55 EDT
Description of problem:
After updating the kernel from to, system sounds are replaced by clicks which is
a clear regression. Menu item "System > Preferences > Hardware > Volume
Control" that the sound device is "pcsp (Alsa mixer)".
The same holds for alsamixer.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Start GNOME session.
2. Produce system event.
Actual results:
A click is emitted.

Expected results:
The corresponding GNOME sound event is played.

Additional info:
- This issue was present for early "rawhide" kernel of the 2.6.26-rcX
  series until the pcsp device got disabled in the kernel builds.
- 'aplay -D hw:1 /usr/share/sounds/phone.wav' does play the correct sound
  whereas 'aplay /usr/share/sounds/phone.wav' does not.
- Whereas other systems might produce meaningful sounds using the PC
  speaker, the NVIDIA nForce™ 4 chipset does not.

snd-pcsp got blacklisted by default and then re-enabled in rawhide (bug 452748).

I guess we should just not build it in F8 and F9...

Disabled the driver in
Comment 3 Joachim Frieben 2008-08-25 03:47:05 EDT
System sounds are back although disabling the snd-pcsp driver is nothing more than a temporary workaround. One clearly wants to be able to use the internal speaker but it simply should not be the default device.
