Upon further inspection, m4a files are having replay gain applied. The issue persists on mp3 and opus.

It worked for all but the ones with the wrong tags:

The tags in the example (m4a) don’t seem wrong, they are read correctly by picard, kid3, ffmpeg, feishin, tempus, and audacious. Neither does anything seem incorrect while looking at the metadata in a hex editor.

For the rest of the non-flac tracks, replay gain seems to be applied in the logs, but is not audible during playback, causing them to play much louder.

Could this be something device specific? I am using a Pixel 9 with GrapheneOS.

Update:
Enabling the option Prefer internal decoder has fixed the issue, so it must be specific to GrapheneOS or the Pixel 9.
