First of all i would like to say hi

I'm just about to purchase a linux system but need a little help..!

What i want to do is create a linux system that can playout serveral different types of audio at once. I'm trying to find out and need some help sourcing a sound card with around 10 i/p's and 10 o/p's that is compatible...

Can anyone point me in the right direction because i haven't a clue...

Thanks in advance

Jason
