Hi folks, I'd spoken briefly about this at the Audio mini-summit at Dublin, and promised to send out a link. I've been working on a tool to automate translating Android mixer_paths.xml to UCM that PulseAudion (or CrAS or anything else) can consume.

I've now written a bit about it at:

The code is up at:

I'll try to provide a quicker way to take this stuff out for a spin than building it yourself soon.

Cheers, Arun
