I am not sure if this function exists, if it is missing or if it is a bug. In any case, it is apparently available. I don’t think it’s urgent.
When I play a radio station and search for the artist using the three-point menu, Volumio does not find any results.
When I play a flac of my collection on the NAS, Volumio only finds results from my collection.
It would be a great feature if results were found on Qobuz, Tidal, Spotify etc. when I listen to a radio station or something from my collection.
