[Bug 1286021] Re: 2.1 surround support (userspace)


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 (
/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. (
