Sound refuses to work. [solved]

[a2gentoo]

I give up. I need help. My sound just refuses to load properly

I am running 2.6.14-r2 with the Kernel ALSA drivers. But I get this message.

What is the output of dmesg and /var/log/messages? (in terms of ALSA obviously)

At first glance of the output it looks like a module associate with alsa, specifically the oss module, is having issues. Just a guess. I would say remerge all the alsa packages and see if that fixes it. Perhaps youre using older versions of them?

[a2gentoo]

I tried what you said. It doesnt seem to work.

I re-emerged the software and then started alsasound manually

Then, just to see. I stopped it. This is what I got.

Are you sure you have built the kernel with the correct sound card suport. Also there is a OSS emulation module whitch you should have as some things need the OSS API. Cant remember what it is called but it is someware in the alsa tree.

The other tinkg you may wish to give a go is coldplug. This will try to automaticaly load modules at startup.

ftwig: i already listed the alsa packages further up.

Okay, so it segfaulted. Um... great? Eh. Did sound work when alsasound was started?

If not (and im assuming not ) give me the output of these:

[a2gentoo]

CarNinja. it has worked with Gentoo in the past. I recently did a complete rebuild of the system from 2004 to 2005.1 (seemed like a good idea at the time). I also wanted to strip Kaffene from my system and succeded in that.

I wanted to use Gnome. (wont go back to that personal reasons).

As for what is going on here is the output.

[a2gentoo]

The answer was to turn off the Kernel ALSA drivers and use those in portage.

I pulled ALSA out of the Kernel. Re-compiled. Re-booted. The emerged alsa-drivers

BAM !! It worked fine.

thanks to all
