My sound card has more than one channel audio source. Is it possible to access the other audio channels? Seems that the “setSource” function always defaults to channel 1 and 2 of the sound card. Anyway to set to channel 3 and 4 or better still get the stereo mix of all the channels on the sound card?

Appreciate any help or suggestions. Thanks!

Listing devices gives:
