No sound on new installation (Fedora 10, GNOME)

[xyz000]

Hi,

I have a clean installation of Fedora 10 + GNOME on a desktop with a Crystal sound card. The card seems correctly detected according to lsmod:

$ lsmod | grep snd

snd_page_alloc         11016  2 snd_cs4231_lib,snd_pcm

The problem I have is that the GNOME app for configuring sound (System->Preferences->Hardware->Sound) does not list my card and the PulseAudio app (Sound & Video->PulseAudio Volume Control) shows that I have only a "null" device available.

I've tried playing a WAV file through the Totem app and I get no sound.

Any ideas? Thanks.

Have you tried to unmute everything in Alsamixer?
System->Preferences->Hardware->Volume control

Have you tried to unmute everything in Alsamixer?
System->Preferences->Hardware->Volume control

Everything available is unmuted. When I open Volume Control I get a dialogue box with a list box labelled "Device" and a tab control. The "Device" list box offers me the following choices:

Playback: Null Output (PulseAudio Mixer)
Capture: Monitor of Null Output (PulseAudio Mixer)

If I select the "Playback" option then the title of the tab control becomes "Playback". The tab control shows one stereo volume control. The volume is set to maximum. The speaker button is set to unmute.

If I select the "Capture" option then the title of the tab control becomes "Recording". Again the tab control shows one stereo volume control. The volume is set to maximum. The speaker button is set to unmute. The microphone button is set to unmute.

Still no evidence of the installed sound card though. What should I try next?
