well I'm only guessing as i've never done this myself, but I'd say the best route is to make a virtual asound config file that treats the two soundcards as one large one (check google for how alsa can use two cards as one).  then chuck should have no problem using that macro device as a four channel output.

Hi<br><br>I&#39;d like to have four outputs with linux chuck. However I only have one<br>onboard (2 channels) and an usb soundcard (2 channels). So the question<br>is: can I use these two soundcards as a four channels device in chuck?
<br><br>Actually I only need dac and something like dac2 (the second soundcard).<br>The idea is to have chuck generate click and sendit on one card, and the<br>other is the actual music, which goes to the PA...<br><br>--
