Denon AVR & Sony BR Player: No Changes but Suddenly No Sound from Blu-Ray Player

Can you check that the HDCP handshake is taking place?
It’s possible that the AVR is not passing this through

I think another tech-savvy head should have a look.  Pity I’m in CT

How can I check that?

An update here: I've used the optical port on the back of BR player directly into the AVR - the sound is back.

I'm still determined to get to the bottom of the no-sound-via-HDMI issue, though, so if anyone has any ideas about how to rid myself of it, I'm all ears!

[Steve]

Further update: the optical cable solved the sound issue but something else incredibly irritating has reared its head. Every time I rewind the BR player and press play, the AVR changes mode to TV Audio (ARC). This happens on every occasion without fail. I suspect I need to fiddle with the TV's settings.

To add to the original problem: the entire issue, including the update in this post, never occurred with the Samsung LED TV I used previously. In fact, the problem never occurred with the LG OLED before, say, two months ago.

I'm still hugely puzzled and am open to any ideas and help from anyone at this point.

[Steve]

I still haven't been able to resolve this issue.

I should add a note on another strange occurrence since the firmware update to the AVR: after pausing and rewinding using the BR Player's remote, when I press the Play button, the AVR's input jumps straight back to TV Audio, as if the AVR is expecting an input from the TV's native Netflix or Prime Video apps. This happens every single time the pause-rewind-play motion happens with the BR Player...

I remain flumoxxed.

Maybe changing out the HDMI cable for
another one, might help, they like giving problems
Just my two cents

That was one of the first things I tried, Robert, but thanks for the guidance. Even using the same HDMI cable to connect directly to the TV produces both video and audio. This weekend, I'm going to remove the TV from the equation and replace it with my bedroom TV to see what effect that has, if any.

There were a batch of Sony players that were bricked after a firmware update that occurred automatically.
Sad but nothing you can do.

Really? When did this happen? Reason I ask is that my player was never connected to the web and there hasn't been a firmware update released for it since 2014. I updated my player years ago and when I recently tried to update the firmware as part of this troubleshooting process, it was up-to-date.

I suspect that a firmware update to the AVR caused this problem.

A further update:

A forum member very generously offered his Samsung BD player, which was for sale and has since been sold, to me for testing purposes.

When the Samsung BD player is plugged into the 'DVD/Blu-Ray' HDMI input on the AVR, both sound and video are present. It seems that it's my Sony BD player which is causing the loss of audio. The reason for the sudden loss of audio from the Sony remains unknown...

However, the sudde/uncontrolled TV Audio switching still occurred when the Samsung BD player was plugged into the 'DVD/Blu-Ray' HDMI input under exactly the same conditions as when the Sony BD player was plugged into the same input. When I moved the Samsung BD player over to the 'Blu-Ray' HDMI input, the sudden TV Audio switching issue no longer occurred and both video and audio were present. It seems that the TV Audio switching problem is on the AVR's side.

Homemation wants to have a look at the AVR to investigate further as they've never encountered this problem before.
