I was thinking to pass this information from snd_pcm_t->private_data. This gets copied to substream->private_data internally which would reach the driver.

In the trigger function - I see that from substream->runtime->private_data, voice specific parameters are extracted. How and can somehow user space fill in some private data to the driver so that driver can process voice in a different way and music in a different way? > What exactly do you want to do differently?
