i use alsa output plugins in xine, mplayer, ...
programs need to use the alsa api, not the /dev/sound oss(?) api. that's
why vmware doesn't work (quake3 or unreal also) here too but its better
than nothing.

i think alsa will be standard for all progs in the not so far future...

its a file for the alsa driver.

no, i guess hw means hardware and not hostname. my hostname is lap.
