fedora 10 update seems to nuke my sound

I did a fresh install of Fedora Core 10 and have had no sound since then.

The result of lsmod |grep snd is :

I also did an alsa-info and the results are at this url :

http://www.alsa-project.org/db/?f=71...88c0003170c081

Also alsaunmute gives :

Unknown hardware: "Audigy2" "SigmaTel STAC9721,23" "AC97a:83847609" "" ""
Hardware is initialized using a guess method

It recognizes two sound controllers, the Audigy one and the Intel ICH4. Could this be the reason for the problem ?

Simulationist,

Looks like you have a conflict between the on-board audio and the sound card.
Depending on your motherboard there are 2 main ways to disable on-board sound:
1. Using the bios setup when the computer is booted up.
2. With a jumper setting on the mobo itself.
Check your motherboard manufacturers documentation to find which one is relevant for you.

Good Luck

Thanks for the response, I will try this tonight and let you know.

I disabled the Intel Soundcard but I still have no sound. The results of alsa-info are here, http://www.alsa-project.org/db/?f=b0...0d87c6a0e2b49a

The other commands have the same result as before. It seems pulseaudio is not turned on. Could this be the reason ? How do I turn it on ?

Thanks.

Simulationist: Try System > Preferences > Hardware > Sound
Several dropdown menus will usually show 'Autodetect' as the default.
Try changing to Pulse Audio and testing.
Good Luck
