Volume Normalisation

[Tim Curtis]

The renderers are individual playback applications with their own volume control mechanisms and they are separate from MPD. Spotify Connect (librespot) for example has an option to set the initial volume when first connecting.

I'm not aware of a similar option for Airplay (shairport-sync) but here are all the options in case I missed something.
