I have my new Sony A8 connected to my Sony STR-DN1040 receiver via HDMI. I use it for ARC audio from the TV. I never, ever want to use the TV for audio. I want the TV to be a screen only and I do not want it controlling my receiver.

The problem is that when you switch the TV on, it will change to TV audio and you need to manually change it to the receiver. This sometimes messes with the audio output quality (eg. I'd get DD 2/0 instead of DD 3/2.1).

There seems to be no setting on the TV to prevent this. Once you set the TV up for the external receiver it wants to take over control for this. Is there any way to switch this off??
