DVBT - No audio on 9HD and 10HD channels through my AVR

[Chigurh]

I wasn't sure which forum to post this in. Hopefully there is a simple fix by changing a setting in my TV or AVR. The topic title says it all really. I don't get any audio from my AVR on 9HD and 10HD FTA DVBT channels. Audio works on all networks through the AVR except for the HD channels of the Nine and Ten networks. If I turn the AVR off, there is audio through the TV speakers from ALL channels. My TV and AVR are connected via HDMI ARC. I'm not sure if it's relevant, but my AVR is only two channel. Any help appreciated.

 

TV: Panasonic FZ950 OLED

AVR: Denon DRA-800H

I have just noticed that HD channels on the Seven network are effected as well. Basically any HD channel with Dolby Digital audio will not play though my AVR.

Fixed it! I found the setting in my TV's setup menu.
