So when I’m watching TV and everything is working when I adjust the volume it states on screen “audio system volume +\-“ but the white Sonos light also flashes so it looks like it’s operating the TV volume as well as the IR sensor on the Beam. Today when it’s not working properly the Sky remote will work and adjust the TV volume on the Beam as it IS connected via HDMI ARC but won’t work when TV is off and streaming music. 
With regards to IR interference it is in a south facing room and it was very bright today….so my question is…once the IR sensor is overwhelmed/puzzled/stops working could it be due to a change in brightness/excess sun etc?? 
Maybe some clear tape over the IR sensor to limit any interference?? 

The real test to do here, is if things work when the TV is off and in standby mode. Play some music to your Beam with the TV off and adjust the music volume with the TV remote - if it doesn’t work then you know the control of volume was ‘highly likely’ via HDMI-CEC and not the Beam’s IR Receiver.

Are you absolutely sure the TV remote is infrared and not a wireless RF remote? - it will almost always work over HDMI-CEC with the TV on, that’s providing that a TV peripheral, connected to another HDMI port, is not stealing the focus away from the Beam. Which I think might be happening in your case and you’re maybe looking at things from the wrong angle. (Perhaps🤔?)

If the TV remote has mic/voice control for any kind of voice assistant (just as an example) then it’s unlikely to be connected over IR to the TV.

So with TV off the Sky remote (which is Bluetooth and IR enabled) works to control volume on the Beam when streaming music. Now it’s all working I went back into remote control setup on the all and this time it will recognise the remote if I set it up as a new remote control. When is stops working it just doesn’t receive the IR from any remote and it won’t let me set up any kind of remote. It’s simply the IR sensor stops working until I power cycle

Yes, disabling CEC is often very helpful. Another trick is to claim to the TV and SKY remotes that they are controlling the Volume on a fictional A/V receiver, then train BEAM to use those IR commands. This will prevent the TV’s own Volume control from responding to Volume commands. This will downgrade BEAM’s utility slightly, but most users will not notice. Unfortunately, some TV’s will not present advanced audio formats when their CEC is disabled.

You might have lost me a bit there. I have a CEC-less HDMI adapter so I might try that tomorrow.

I’m not a SKY user. Most TV’s support using their remote’s Volume buttons to control an A/V receiver. In this mode most devices will send IR Volume commands regardless of how the remote communicates with its device.

In this case, select a model XYZ as your target A/V receiver, then train BEAM to respond to these IR commands.

I also have an alternative suggestion you can also perhaps consider trying, but this is only if you wish to leave HDMI-CEC enabled…

Note: Always try to setup the sky remote on Sonos with the TV switched off/in Standby-mode - you could, I think, leave the HDMI-CEC protocol in situ on all devices and setup the sky remote to control a ‘fictitious TV’ not the actual make/model of TV that you have.

The TV volume/mute should still work anyway (hopefully) via the sky-box HDMI-CEC connection to the TV… and then see if that new IR code perhaps works any better for you? 

Just give the sky remote an entirely different TV IR code. Oh and of course reprogram the Beam with any newly-assigned IR code too. 

If it proves to be no better than before, then just revert the remote back to what you have now.

Then if the IR control still continues to fail, (always check this whilst the TV is off/in standby mode) the next option will likely be to submit two system diagnostics, one with, and one without, the IR working on the Beam and make a note of the Sonos submission reference numbers and then contact/chat to Sonos Customer Support about the issue via this LINK.
