I found out that this also happens in the IOS browser and it is also reproducible on other IOS / IPadOS devices, so this seems to be an IOS bug.

are you using transcoding for this?

[piekay]

No, I was using full quality FLAC files. Converting them to ALAC using FFMPEG fixes the issue.

I have also tried playing the FLACs directly, same issue. This seems to be an error with how IOS decodes FLAC audio

[piekay]

So when using FFMPEG to transcode the song from flac to flac the issue no longer happens, so this seems to be an issue with the native encoding of that Album / file specifically

Maybe it would make sense to add this as a known issue to FAQ that this is an encoding / decoding issue and add a short explainer on how to reencode music with FFMPEG
