I had problems with latency in Volumio2. When i pressed play on my Mac there was a 1-2 sec delay till i could hear the audio trough my Speakers.
I managed to fix that by adding this in the /volumio/app/plugins/music_service/airplay_emulation/shairport-sync.conf.tmpl file:
After changing this Video playback, e.g. from Youtube, is not in sync with the audio. The Audio source is always 1-2 seconds ahead.
Do anyone now how i manage to get Audio and Video Playback in sync again?
