I get that you’re passionate about CUE support. But calling it ‘insane’ to not include it might be a stretch. Let’s talk features and facts, not insults.
Volumio & CUE File Support
Volumio has officially dropped support for CUE files , primarily due to MPD’s sensitivity. Improperly formatted CUE sheets can crash MPD, and the risk outweighed the benefits. If you rely on CUE for gapless playback or track indexing, consider converting them into properly tagged individual files instead.
Not stating that it will never come back, but that fully depends on MPD’s stability.
