On a Dell Latitude D800, the sound card is detected by alsa (Detect Sound card from main menu) but no sound can be heard. With a old kernel (probably 2.6.11-1369_FC4), the sound card was ok. But with the kernels 2.6.12-1456_FC4 and 2.6.12-1447_FC4, sound card does not provide any sound.

I have found a way to make it work (on a forum: many other persons had the same trouble) : using alsamixer, turn all volumes to maximum and mute and unmute all devices. And then... the sound card starts singing... Seems that something is mute after installation but it does not appear in alsamixer.
Could you please attach output of "amixer" when sound works?

It should be fixed in rawhide.
