Paul. I know all that. I am just lacking the knowledge of how to link the output stream to a dedicated channel.

That's possible. (Don't expect me I to startup discussions about quality of Alsa documentation etc., Alsa I regard as designer territory - I am just a poor user.)
if you want multiple apps to send independent streams to a device, you
have 3 choices:
1) use dmix
2) use asoundrc to set up pseudo-devices mapped to distinct
channels, and have each app use a different pseudo-device
3) use a sound server that knows what its doing (JACK being one example)

if you want a single app to send independent streams to a device, then
the app has to know what its doing.
its not any simpler, or more complex, than that.
Pretty simple - You IMO still did not answer the question. How about an example for 2) ?
For now the only way to sent a stream to e.g. the out3/4 of HDSPmixer without going for 1)2)3) has been a multichannel wav.
