In such way it's possible to control each speaker independently, programs like xine can take advantage of this. Then, whatever you want to do is just a software issue. It's not possible to send the same output to front and rear just via a simple "aplay ...", maybe it's possible to do magic via the .asoundrc stuff crearting a virtual device, but I dont know how to do that. /Benny ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf
