Music files with the .M4A extension cannot be played using Hi-Res Audio Player.

    If the audio file format is AAC even though it has the .M4A extension, the music file cannot be played as Hi-Res Audio Player does not support AAC file format.
    A music file with the .M4A extension is supported only when the audio file format is ALAC.
