Status update: For alsa-lib, the surround21:x name is in 1.0.28, and 1.0.28 has been released into utopic.
For pulseaudio, not much has happened. The patch to use the "surround21:x" name is in PulseAudio git ( http://cgit.freedesktop.org/pulseaudio/pulseaudio/commit/src/modules/alsa/mixer /profile-sets/default.conf?id=3f140f9022ef0b59b3684edd25e2202a65989669 ) but there has been no upstream release of PulseAudio since this patch went in. There has been some upstream discussions about how to best implement an LFE filter, but nobody has finished writing one yet.
