I am looking for a way to create a virtual sound device in Linux, which would use channel outputs of my sound card.
I have no experience in Linux and therefore am asking more experienced users for help. I have latest Ubuntu Desktop 10.10 installed on my VirtualBox machine. What I want to do is to be able to create multiple virtual audio devices and then configure them to use different output channels of my M-Audio ProFire 610 sound card. The reason I want to do it is that I will use these devices in Java afterwards, and Java doesn't support directly selecting channels in the sound card, therefore I need to do it outside of Java.
In OS X I can do this by messing arround with Audio MIDI Setup utility, maybe there is something ready made for Linux, too? This is how it looks on OS X:
I am looking for any help, hints, tips - well anything that will help me achieve this.
