Issue description
When playing different tracks, the audio normalization gain calculated and reported by jellyfin is not applied in symfonium. I think it may not be being sent in the format symfonium is expecting (since logs from a prior similar support ticket had REPLAYGAIN_TRACK_GAIN reported, which mine doesn’t, and I didn’t see others mentioning this “NormalizationGain” thing that I see in my logs), as I can see in the logs:
2026-06-03 05:40:14.752 Verbose/ReplayGainParser: No gain tags found
2026-06-03 05:40:14.752 Verbose/ReplayGainParser: Final gain: 0.0
2026-06-03 05:40:14.753 Verbose/ReplayGainAudioProcessor: Volume [0.0/0.0]: 1.0
But also in the logs it seems jellyfin does report a ‘NormalizationGain’ (which corresponds to the gain that is correctly applied when I use the Finamp client to play the same track): 2026-06-03 05:40:08.974 Verbose/JellyfinLogger: <-- [705] {"Name":"Easy On Me",...,"LockData":false,"NormalizationGain":-8.6}
It would be really nice if this ‘NormalizationGain’ could be used in symfonium. Let me know if there is something I can do on my end to make it work with that tag.
