[PD] Channel output

Try running pd.exe -listdev to take a look at the audio devices 
available to Pd. If you're using ASIO you should do -asio -listdev. Then 
in your .bat, or in the command line specify -audiodev 1,3,5 (or 
whatever numbers and order you want) according to the numbers that 
-listdev gave you, which should be the stereo pairs of your card (as I 
remember my m-audio quattro was like that).

I do seem to remember some problem with the numbers a while back in 
Windows, though, where they were 1 out of place, so that a device listed 
by -listdev as "0" was actually -audiodev 1. But I haven't used Pd in 
windows in a while, so that may have been fixed.

Hope that helps,
