i have a santa cruz too, and it was a pain to get working, until i found out how, and then it was easy.
anyways, for simultaneous sounds you need something like ESD (enlightenment sound daemon), which is supposed to let you do that, but after messing with it for a bit, it still wasnt working so i just said screw it. the only time i have 2 sounds going at once is when i wanna watch a video or some flash or something, and at those times i dont want my music going anyways.
for the 4 speakers, i have no clue, as i use a pair of 22 dollar labtec speakers
and just by chance, does your sound randomly go to crap? i mean, one song will stop playing, then the next will start, and its all crappy sounding, like its being played at a really low sample rate like 11khz or even lower. and the sound stays like that until i fix it. to fix it i wrote a little script to remove and then insert all of the modules again. it looks like this:
#!/bin/sh
sudo modprobe -r cs46xx
sudo modprobe -r ac97_codec
sudo modprobe -r soundcore
sudo modprobe soundcore
sudo modprobe ac97_codec
sudo modprobe cs46xx
sudo aumix -v 87
sudo aumix -w 78
echo "sound fixed sucka!"
exit 0
i just assigned that to a key binding, so its not too bad anymore. i just stop my mp3, hit alt+shift+F, wait a second, and then start my music again. really wierd though, do you have the same problem?
