,m4a playback 2x faster

[Bat23may]

when I play the song better off worse it is sped up but when its a mp3 file the speed issue isn't there. I have no idea what could of caused the speed issue as both files play fine when listened any other way.

Which OS/platform do you use? I imagine the problem is in kira/symphonia side because LRCGET doesn't really handle the media playback part.

I have weirder issue with m4a, precisely ALAC one XD

In a nutshell, I store my music as ALAC because I wanted my collection to be sync-able with Apple Music. Some files have Hi-Res format with a bitdepth ≥ 24bit, and it made the player runs extremely slow.

Here's snapshot and mediainfo of the file I'm trying to play (notice the total playback in player)
