From the last couple of days, I have been trying to understand the Linux Alsa Subsystem.I have read the Alsa Driver API and Application API's. But I could not understand the concept of PCM substreams,
A PCM stream has one or more substreams. Multiple substreams are used when the hardware can mix them together for one output. This was used in old wavetable sound cards; nowadays, you almost always have one substream.
