Thanks for the patch. Unfortunately, it is not sufficient for gr-fcd
because it must also work on BSD, Windows and OS X. As such no ALSA or
linux specific code should be in the gr-fcd block itself.

In my opinion, updates should be made in gr-audio. We need a new API
call that returns a list of available audio devices with their
descriptive names. That way we can implement autodetection in a
platform independent way.
