There are 2 different types of multichannel audio hardware:
1. External MultiChannel Audio Hardware
These cards can be addressed in vvvv only using their WDM drivers which always only offer to use their channels in pairs of stereo. These pairs (like 'Channel 1-2', 'Channel 3-4', ...) are exposed via the Driver pin of the AudioOut (DShow9).
Addressing the channels of such a hardware individually only works using ASIO drivers which are not supported by vvvv's native DShow9 nodes but only via the VVVV.Audio.Pack or the the BASS plugins provided by vux.
2. Built-in 5.1 or 7.1 Surround Sound Cards
