This is a pretty weird occurance for me. I've run into alot of problems concerning sound, but none like this before. My sound is working fine, it's crystal clear, it's just the right volume, but the problem is it's lop-sided. By that, I mean there is no sound coming out of the left side. It's like if you had the balancer set all the way to the right. (no, I don't... I checked with aumix numerous times.) Honestly, I have no clue where to begin with this... or if it should even be in the hardware forum. Hehe.
Set-up: Gentoo on 2.4.26 kernel (uname -r == 2.4.26-gentoo-r9), Sound Blaster Live! sound card (emu10k1 module), using the aumix mixer. Problem persists in mp3blaster, xmms and mplayer (both movies and mp3's.)
Edit: After putting my two left speakers to me ear, I've found that they are putting out sound... they just aren't nearly as loud as my right speakers (so quiet that they have to be next to my ear
