Yes. > I figured I had to be doing something wrong that it didn't work :( Do > you happen to know what the sysctl is for this? :) Not exacly (can't look it up ATM)... there are two. One is for setting it to a specific number of virtual channels, and one is to let the sound system automatically add some upto the amount you allow with the sysctl. It's in the sound-MIB (hw.sound?). Do a "sysctl -a | grep pcm". If the output is "hw.sound.pcm0.XXX" run "sysctl hw.sound" so see a complete list of sysctl's available. Pick one of the "vchan" ones and change it from zero to an arbitrary numer... e.g. 4 to be able to let 4 applications play at the same time. I think we should activate vchans by default... anyone with an idea of the number of channels we should provide by default (warning: bikeshed ahead)?
