New user to MusicBrainz, so my apologies if I’m missing something obvious!
I have a deluxe Blu-ray disk that contains multiple version of the same track (stereo, 5.1, new mix, etc.). I only ripped the 5.1 version. When I lookup these tracks in MusicBrainz Picard, it identifies them as the “Stereo Mix” rather than the “5.1 Surround Mix.”
I can’t figure out how to edit this so that it is tagged as the 5.1 mix instead.
