ALSA and AC97 : the solution

rieger · Posted: Fri Jul 05, 2002 5:54 pm Post subject: ALSA and AC97 : the solution

don't know exactly if this is the right forum but:

as many other people, struggling with Alsa and ac97 (or via82c686) and browsing all 101 messages concering alsa in this forum I tried something I didn't find in the forum and it worked, so it may be usefull for others.

here it is:
use snd-via686 instead of ac97_codec or whatever, thus, snd-via686 in modules.autoload and as alias for snd-card-0 etc (as in the Desktop guide)

no suddenly amixer worked and you can unmute the stuff.

rc-update failed however, but I've got sound

I've added amixer set Master 100 unmute (and same for PCM) to local.start

because rc-update add alsa default doesn't work n my machine.
I'v tried add alsasound instead but still no sound when rebooting.

the local.start option is a fine temp. solution for me, but when someone knows the right way to achieve this, I'd like to hear it.

"rc-update add alsasound default" should automatically save and restore volume settings across reboots.

I see on the ALSA site that they say the driver for the sound card is 686a
"VIA via82c686 via686a" This is from the "sound card matrix" which can be found here: http://www.alsa-project.org/~goemon/

So my question is this, did you modrpobe via686, or via686a? If so is one the ALSA module and the other the native kernel module? Does anyone know? Also if you did truly modprobe via686 can you modprobe via686a and still get it to work??

I am still having lots of trouble with ALSA and I am just trying to get it all figured out! Thanks in advance!

Regards,

Ok, I have an AC97, and I'm about to compile my kernel, I'm reinstalling Gentoo at the moment (various reasons).

My question is, what should I compile into the kernel in terms of sound support?

rieger · Posted: Sat Jul 13, 2002 6:51 pm Post subject:

-sound support enabled.
-ensoniq 1371 Es (the thing that's already selected) as module
-OSS support as module.

those are my settings

the only thing I would say that you would need built into the kernel is sound support, and if you aren't using the alsa modules, then create modules for your sound board. because as for oss stuff, alsa will take care of that itself, since it creates modules for an interface with oss apps.

Well, I've just tried "modprobe snd_via6986" and he can't locate the module ... in "/lib/modules/2.4.19~/" is even no folder names "misc" ... uups. Can anyone tell me what happened?
