no sound fedora 7 with intel sound card

Hey,
I am running fedora 7 on a compaq laptop. My problem is that there is no sound over here.

kernel is the default 2.6.21 and lspci gives

Quote:

00:1e.2 Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 04)

I am pretty sure that this card is supported in linux.
lsmod | grep snd gives

soundcore 11553 1 snd
snd_page_alloc 14472 3 snd_intel8x0m,snd_intel8x0,snd_pcm

Maybe this is the problem because OSS is being used? I have found that on most comps with intel onboard audio the snd_hda_intel modules are used.

Any help would be nice.

Hi, I had problems with the same intel audio hardware with my gateway. I run Kubuntu, and I found this...

https://help.ubuntu.com/community/HdaIntelSoundHowto

It is Ubuntu specific, but I believe there is enough info there to get you up and running. The big point would be to install the latest alsa drivers, and then telling fedora to use them. Down towards the bottom, I had to put "gateway" in place of MODEL in this line....

options snd-hda-intel model=MODEL

in /etc/modprobe.d/alsa-base

The file is heavly commented, so you should be able to figure out the right setting for your laptop....

Good luck...

David

P.S. You might want to upgrade to Fedora 8, as it may have out of the box support for your soundcard already, then again, maybe not too...

Good luck

ok I blacklisted intel_8x0 and modprobed snd-hda-intel didn't work out. I am trying all there is in the page , but I don't have much hope.
