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).
Mixed in alsa or should be mixed by device?
