I am using ALSA and it appears to work except that only one program can access the sound hardware at a time (so is just like OSS :-)). If I am playing music in XMMS and then try to aplay a .wav file, it will hang until XMMS is closed for example. The trick of altering the HZ of mp3 plug-in to remove the choppiness doesn't seem to work for all mp3 files (thought does for the vast majority). Many thanks for looking into this (and all the other work you do -- sleep support, for example, has been *incredibly* useful)! best regards, -- Matthew T. Atkinson
