This is the correct place, but I've been busy with other stuff to push our configs upstream to date (will do so today now). The eventual contents of this repo are intended to be copied into :-

/usr/share/alsa/ucm (or where ever alsa is installed on your distro)

However, I've not had a chance to push the UCM Nexus and Pandaboard files from Arun to this repo yet due to some other ongoing work.

FYI, Arun's current UCM configs are here :-

http://cgit.collabora.com/git/android/platform/external/collabora/pulseaudio-android.git/log/data/alsa/ucm/Tuna/VoiceCall

Interesting idea to create separate shareable codec UCM configuration. We currently have no way to "include" a shareable codec specific configuration into a machine specific configuration but it would probably not be too hard to add to the parser.
