Description of problem: After updating the kernel from 2.6.25.14-108.fc9.x86_64 to 2.6.26.2-14.fc9.x86_64, 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): 2.6.26.2-14.fc9.x86_64 How reproducible: Always 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 2.6.26.2-16
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.
