Wd live won't play AAC audio

Hey Mike,

Thanks for your response.  Funny thing happened.   The following day after I received your response, the files played fine.  Made no changes of any kind and they played without a hiccup.  Thought everything was fine, but now the WD Live won’t play the audio for a DTS MKV and an AC3 MKV.  I have a support ticket in with WD as I shouldn’t be having these problems.  Both the MKV’s play fine on my PC, so I would assume the WD would play fine.  All files are played via USB.  Could there be an encoding problem I need to work out?  I’m getting close to returning this unit, so any help would be greatly appreciated. 

Thanks for your asisstance…John
