In my opinion, support for AAC make sense only in passthrough mode. E.g.
when your music files are already stored in AAC and you have headset
with AAC support; and you do not want to re-encode it twice.

But I do not see support for passthrough mode in this patch. It is

Maybe similar thing could be useful for MPEG1 A2DP audio codec (as lot
of people listen MP3 files), but I have not seen headset with MPEG1
