Squeezebox Players

[jimrushy]

My Squeezebox Touch can't open M4A (aac) files however it does open my M4A (alac) files.

Server is a Netgear ReadyNas.

It is only the Squeezebox Touch that won't play them.  Other devices running Squeezeplay are fine. 

I have factory reset and ensured latest software is applied.

Any help would be much appreciated
