[Haikal]

Hi,

I have two sound card in my computer. I make two pipeline that play
two different file. I want each pipeline play on different sound card.
How do i determine "pipeline 1" play on "sound card 1", and "pipeline
2" play on "sound card 2". I write the code with python in linux. But
if someone have answer in different programming language or os, i
would be very appreciate it.

Thanks.
