I am ramping up on ALSA architecture and framework. I have a couple of basic
questions. I apologize if these questions are very basic to be raised in
this mailing list. If anyone can help me find answers, it would be great.
Thanks in advance.

1. My assumption is that ALSA handles only PCM streams today. Does it handle
encoded streams from application to sound card (Which can do hardware

2. What are the hwdep files in ALSA used for? Where do the concerned IOCTLS
land to?

Thanks and Regards,
