Status/Audio

Current status

• We have yet to figure out device policies: what to do on jack unplug, what to do on jack plug while listening to music, what to do on jack unplug when you're on a phone call, etc.

Development notes

For each device, we'll need to create usable Alsa UCM files. And we'll need to learn a bunch about pulseaudio's routing and policy management, how to act on certain plug events, etc.
