alsa problems - sound only in one channel - emu10k1

[PennyroyalFrog]

I'm having some alsa problems. since i updated to alsa-lib-1.0.8 i only get sound in one channel (the right one), Kmix crashes on boot, and kaffeine crashes when trying to open anything with audio (other media apps work fine). I use SB Live! emu10k1. i tried updating to masked versions of alsa-headers and alsa-lib 1.0.9_rc2 and that fixes the crashing problems with kmix and kaffeine but the audio still only comes in on the right speaker. i would like to go back to previous versions of alsa-headers, alsa-lib, and alsa-utils. but i'm not really sure how... i tried putting them in /etc/portage/package.keywords but it still only downloads the recent versions. what in there is as follows:

I fixed the problem... i ran 'alsaconf' and everything works fine now, although kaffeine still isn't working perfectly.

calling alsaconf isn't exactly a solution, it propably just reset mixer settings which solved the problem.
I believe you get this problem if one of the two mixer-items "EMU10K1 PCM" is set to 0 (please note that those mixer-items might have a different name in different alsa-versions)


To downgrade to a previous version, put the newer versions you do NOT want to install into /etc/portage/package.mask like this:
=media-libs/alsa-lib-1.0.8
That would prevent emerge from ever installing alsa-lib-1.0.8 and if that version is installed it would up- or downgrade.
