You can use the IEC format for MPEG and use an ALSA driver if you
wanted and can afford the bandwidth waste and payload overhead.
We've been also playing with the notion of a new API, similar to ALSA
(ring buffer, periods, etc), but where references to samples/time
would be removed (all byte based). If there's enough interest in the
community maybe we can share this.
