gentoo + alsa


after doing some heavy reading on the gentoo website, i thought i had alsa down for sure. i've built the alsa drivers, i've got my soundcard's modules all loaded, fired up several different media players, bam - no sound.

i've unmuted channels with amixer - including 'headphones' and still no sound. how can i be sure all proper channels are unmuted?

yes, my speakers are plugged in and working fine. tested them on another box.

When you compiled your kernel, did you only enable Sound card support and nothing else (if you emerged alsa stuff)?

yep. :-)

it's very strange... it's as if it's muted - i mean, there's literally nothing coming out. but i've checked the channels, nothing muted. very odd indeed.

any more idears? :-)

gentoo is lots of fun btw. i'm sure it'll be my main distro for some time.

I think I would ask on the Gentoo forums next.

Although I don't have an Audigy2 (I have an Audigy 1 OEM), with Alsa 1.0.8, I found I had to turn up all the surround speaker channels (Front, Surround, Centre) as well for sound to start working again - a charming little 'undocumented feature' they added...

Perhaps that will work for you?

Edit:

Oh, and disable any optical or digital outputs in alsamixer! (usually by muting those channels with 'm' - look for something like "Audigy Analog/Digital Output Jack"). If they're enabled, the Audigy won't send out an analogue signal for your speakers/headphones.
