Some .M4A files will not play using the Hi-Res Audio Player software

Applicable Products and Categories of This Article

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

A music file with the .M4A extension is supported only when its audio file format is ALAC.
