[alsa-devel] question on hardware mixing

If I need to send a voice stream and an audio stream to the hardware as two separate streams... I just need to open 2 ALSA device from user space and send it right?

If I want to send some private data for each stream (say I want to differentiate that it's a voice/music...for which I did not find any provision) how do I do that?

It does that by default. Just run multiple applications.
