alsa doesn't transparently provide an api like this. it's either
something on top of alsa or approximated by writing a plugin for each
type of codec. alsa plugins are only supposed to know about some very
simple encoding audio schemes though.

ironic that you are making the case for gstreamer at the same time you
say it's limiting. :)

We have the alsa plugin mostly working now. We haven't abandoned that
idea. alsa plugins are relatively simple in what they expose to the client.

i plan to keep improving the alsa plugin and get into gstreamer to get
some of the more advanced stuff. i have a little picture illustrating
how we tear btsco into two projects that go into these two camps.
