Hello there,
My system: - Dell, Inspiron 5100 - Debian sarge - snd_intel8x0 - Self compiled kernel 2.6.7 I've had not so nice experiences (neither dmix nor asym) with it: - Using xmms, if there is a lot of disk usage, audio will stop playing. - Using (self compiled) mplayer, the audio won't play well. Solutions: (better solutions are welcome!!!!!!) - xmms, use xmms through arts (and arts through alsa) - MPlayer, give cache to the default alsa device. Solutions drawbacks: - xmms, arts ain't that good, some audio files will play lossy. - MPlayer, none.
