no sound F7 - Intel ICH8

[pnotequalsnp]

I just installed a fresh version of Fedora 7 but I have no audio (the audio test during install worked). If anyone could give me an idea of what to do I would really appreciate it. Below you will find some info that might be helpfull:

interesting stuff from dmesg

I'm no expert but I think your chip isn't supported maybe. Easiest way out is by a soundblaster. I could be wrong, but that's what I did.

first thing you want to do before doing any troubleshooting is a full system update.

su -c "yum -y update"

Ya -- pick up a SoundBlaster Live! or similar. Kernel 2.6.22- all revs break the PCM device on intel sound cards. FC6 (kernel 2.6.20 or lower) will work with your sound card until you get to 2.6.22.

What do you mean "until you get to 2.6.22". You said that's the kernel version that is broken?

noted in your dmesg:

usbcore: registered new interface driver snd-usb-audio

If you have a USB audio device (including web cam camera) plugged in at boot, you will likely be having same problems as I did >
