Hey, I picked up a USB sound card which seems to be working fine under OSX. I am wondernig if it is possible to use both internal and this usb sound card at the same time? I want to direct certain programs to play out of the USB card and every thing else through the internal. Specifically VLC, Quicktime, and sometimes the web browser. Basically I am looking for something like the windows vista/7 audio mixer, but not only control programs, but be able to send audio to a specific output. Any thing exist? Thanks.
