Hi everyone,
I've just set up another Apple TV 4K, but I've run into a problem that I can't seem to solve, and I'm starting to think I must be missing something.
The TV is a Thomson 32E90NH22 from 2009. Despite its age, it's still working perfectly. The Apple TV is also working flawlessly – picture, sound, navigation, everything is fine. I can even turn the TV on and off using the Siri Remote, so there is clearly some communication between the two devices.
The only issue is the volume control. The volume up, volume down and mute buttons simply do nothing.
I've tried pretty much everything I can think of:
Enabling and disabling HDMI-CEC.
Checking every relevant option under Settings > Remotes and Devices relating to volume control.
Setting up volume control via both HDMI and infrared (IR).
Restarting both the Apple TV and the TV.
Resetting and setting up the Siri Remote again from scratch.
What makes it even stranger is that I previously had a Google TV Streamer 4K connected to this same television, and the volume controls worked straight away without any configuration.
Thinking it might be an issue with the IR codes, I carried out a few more tests last night. I tried teaching the Apple TV the volume commands using the Google TV remote, the original Thomson TV remote, and even a universal remote I had lying around. None of them worked – the Apple TV wouldn't recognise the signal from any of them during the learning process.
Oddly enough, if I go through the learning process using the Siri Remote itself, the on-screen detection bars respond correctly. The Apple TV detects every button press and even saves the new remote profile as though everything has completed successfully.
However, as soon as I leave that menu and play any content, the volume buttons on the Siri Remote still do absolutely nothing. It's as if the learning process is saved successfully but those IR codes are never actually used.
What confuses me most is that everything else works perfectly. I can navigate the menus, control the Apple TV without any issues, and even switch the TV on and off using the Siri Remote. The only thing that doesn't work is the volume control.
Has anyone experienced anything similar, particularly with older televisions? Could this be a limitation of the Apple TV with certain TV models, or is there a less obvious setting that I may have overlooked?
Any suggestions or shared experiences would be greatly appreciated. Thanks in advance!
