Update 01.00.60.B
Just lost TV sound cant get it back.
Picture froze.
Did a power off.
No better.
Surround AAC 5:1 test centre speaker comes out of rear left.
In the middle of a factory reset to get some sanity back.
Will post results when untangled.
Edit:
After allot of buggering about the Picture on freeview came back but no sound.
Freeview recordings have no sound
BBC Iplayer No sound and has the spinning wheel as if the network is very slow.
I am on a decently fast ethernet !!.
I found the the cinema audio was off by pressing the S/AD key on the remote twice.
It complained HDMI CEC was off, I turned it on and removed my Lindy adapter to allow me to press the red key to turn it on.
That done no sound on Freeview etc.
The mute is off on the Aura.
Youtube plays ok as far as I can see.
VLC plays both sound and video , but it all comes out as PCM, even Dolby Digital,Dolby Digital + and DTS.
I am getting surround 5:1 but I have a nasty feeling the channels may be miss mapped and Centre is coming out of left rear.
Freeview was not a problem and now it is.
Too tired to check more , even flattened my remote rechargeable batteries hacking around.
