Help! No sound with Denon AVR-X2000 and new Sony TV :(

[zwaigo]

Hi, I have a Denon AVR-X2000 and have been using it with my previous Samsung TV.
My Samsung TV didn't have ARC so I was using an optical lead to attach and it worked fine.
I have now just bought a Sony Bravia X85C and set it up but couldn't connect to my Denon amp.
My new TV does have ARC and I've got the HDMI in the right slot in the TV and I have turned on HDMI control in the Denon Video Menu.
I've also selected Audio Speakers over Tv speakers in the Sound menu of the TV - but no sound coming through my amp.
What is strange is there is no sound even when I plug in my optical lead from the amp into the TV which was previously working with the old Samsung TV.
Can anyone help or suggest anything? I want great sound for my new TV! Thanks in advance.

Hi, thanks for your help.

Sound comes out of the speakers during Amp setup, but no sound from TV. Only one ARC connector on my TV.

In my Bravia Sync Settings menu I have Bravia Sync Control set to On.
But in the Bravia Sync Devices List my Denon AVR-X2000 does not show up in the HDMI devices.
I am able to send out an 'enable' signal from the Bravia Sync menu but it just says no devices found.
