Re: [alsa-devel] concept of substream...

I was trying to understand the concept of substream. So can we have a device which can have support say 5 substreams and these are controlled (start/stop) independent of each other.

Yes.

At any instance we can have any number of substreams active and runtime we should be able to activate/deactivate a particular substream.

If by "active" you mean opened or running, yes.

Please note that when opening a device without specifying a substream number, ALSA will open the first free one. This implies that all substreams should go the same output (i.e., be mixed together).
