Cannot play M4A Files

My Cloud Home won’t play M4A files through Sonos yet Sonos will play those exact same files if stored in a different location. What is the fix to allow My Cloud Home to play those files? Seems like this is a somewhat common problem but I haven’t seen the fix.


You could refer to the following link:

Thanks @Jonty.S - would you mind referencing the specific fix outlined in the article? I’ve read it previously but don’t see where the fix is outlined for M4A files, it’s more of a general HowTo.

This was the exact same issue, apparently resolved a year ago - Sonos Unable to Play M4A File Stored on My Cloud Home
