Volume mode in the app settings for second generation streamer why

Here you go.

Hybrid vs Variable volume

That screenshot looks pretty clear to me. In hybrid mode the digital volume works just with streaming services. Streaming services are Spotify, Tidal and Qobuz. In variable mode it works with anything going through the streamer, so local files, your nas, internet radio, the TV etc.

You should use fixed volume for best SQ.
