This one only has 3 jacks 1 video and L+R audio. No switch. The audio
outputs are warm to the touch (normal), so I would think the circuit is
working, may have to have another look at the Menu, maybe there is something
there. Thanks for your help.
I think I'll try Ext. inputs to see if audio is there.
