If I define mixer controls to switch between each substream,
I wrote "mixer controls to switch between these settings for each substream", i.e., each substream would have its own flag. [Harsha] I am still not comfortable how to do this... I guess EMU10K1 handle this kind of mixer controls for switching... I shall look into this driver to learn more
can I use snd_pcm_t->private_data to communicate if it's a voice or audio
ALSA does not have a predefined mechanism to set it from userspace. Your driver can initialize it when it is probed, or it can change it when opening the substream. [Harsha] Thanks.... so can I assume that when I open a substream, I can set a private_data to communicate to the driver if its voice/music?
