We would like to support OpenAL and generally 4.0 and 5.1 players and
libraries. Unfortunately, we have other more general problems with
higher priority at this time. Watch this list.

BTW: Why OpenAL uses direct ioctl calls? This method will be never
supported officialy for the ALSA API, because many things are implemented
in the user space and specially generic 4.0 and 5.1 support will be
available only through this library.
