a roon extension to control yamaha's network-enabled av receivers
on fixed-volume connections (like hdmi) this extension lets you access the receiver's volume and mute controls.
i recommend checking roon's docs on how and where to run extensions first. should work with node.js >= 7.5.0.
- manual ip-address not used
- multiple instances seem to be created
- too little error handling
- support yamaha scenes in addition to inputs
- set vol/mute state on init
