From what I understand, this is more of a hardware limitation than an alsa limitation. They claim that some sound cards can do automatic hardware mixing. If your card can't do this then there is a plugin called "dmix" that does software mixing (i.e. allow sounds to play simultaneously) . I've never tried it. Just search "alsa dmix" for plenty of how-to's. I would imagine just using esd or arts would be easier and work flawlessly at the moment. I think a lot of Gnome apps are probably programmed to use esound. Give it a try... it can't hurt. I'm no sound expert by any means so take this with a grain of salt... -- Eric Gaumer <gaumerel@ecs.fullerton.edu>
