[pulseaudio-discuss] [PATCH 2/2] alsa-mixer: Add surround 2.1 profile

[David Henningsson]

Surround 2.1 is one of the more common surround profiles these days,
so it's about time we support it.

The "surround21" was added to alsa-lib a few months ago, and there
hasn't yet been an alsa-lib release since, but I doubt it will change.
