Strange mouse movement

[enchantner]

I'm having lousy audio problems with Karmic. I was told to
export SDL_AUDIODRIVER=alsa
but I've no idea how/where.
It looks like you 'exported' something in the game launcher, which sounds ideal because I'd rather have any workaround affect only Penumbra instead of the whole system.
Please, How exactly did you do that?

Just add this to your ~/.asoundrc :

pcm.!default {
type hw
card 0
}

ctl.!default {
type hw
card 0
}
