Ugly ugly hacks of ugliness
Add ugly, ugly hacks to enable speakerphone/mute buttons
We call pactl synchronously in order to (1) change the sink/source port for speakerphone and (2) mute the sink/source for mute. The sink/source names are hardcoded. This is all ugly and needs to not exist. This functionality should be in Wys, accessed over D-Bus, or in some other, as-yet undefined component.
