Sonos Beam and Bose QC headphones in Samsung TV

Also very interested in this. Any update?

I have the exact issue with LG OLED65C7P with SONOS Beam via HDMI-ARC and Bose QC Bluetooth Headphones.

I paired the headphones to TV, but when I switch the audio output on the TV to "LG Soundsync / Bluetooth", the Bluetooth Headphones work momentarily (3 seconds), then automatically switches back to the Beam on HDMI-ARC. The Bose Headphones still show connected but Beam steals the audio back.

There is a workaround, by going to Settings, Sound, Sound Out, and turning off "Simplink (HDMI-CEC), but this is a pain to do every time I want to use the headphones. You have to re-enable this setting to use Beam again.

Any ideas?

Not that this should be hard for Sonos to reproduce, but it might help to have some diagnostic reports from your systems. If you could submit a diagnostic report after switching your TV's audio output and having Sonos take it back, then post the confirmation number here, I'll point a Sonos employee this way so they can dig into what's going on here.

Here's my diagnostic: 364484165

I make no guarantees that there will be a fix... this could just be how HDMI-CEC functions with regards to external audio devices... but I would think that if you switch away, it should honor that until you switch back.

Thanks MikeV. Sonos Team, Here is my diagnostics report: 1966860244

Sonos sent me a DM on this. They said the Beam was designed to work this way and the solution is to turn off HDMI-ARC on the tv when using headphones or unplug the cable from the Beam. Clearly not ideal - I think this should be able to be ‘fixed’ with a software update.

Yikes. Ok thanks for the update. That doesn’t sound right to me. Guess the best solution may be to program a macro into my Harmony remote to disable arc and switch to Bluetooth and back.

I wouldn't think this is a Sonos issue to resolve honestly. The Beam is completely unaware of the headphone/Bluetooth connection going on between the TV and the headphones. It's up to the TV to understand and determine where it should be sending audio.

I'd be curious to know if the TV turns off all other audio outputs when the ARC connection is active. I might see if connecting a Bluetooth transceiver to the RCA/optical output of the TV will work without manually turning off the ARC connection. You really shouldn't have to do this, but it might be a workaround.

I don't think that is true Danny. Using another soundbar over HDMI ARC, when switching to the TV speaker or headphones on Bluetooth, it respects the change of speaker, where as the Sonos Beam reconnects itself as the speaker when a different speaker is selected. This is a Sonos issue and they have said that they have made this the behaviour by design. Which obviously sucks

I will add myself to this. Samsung Smart TV, 2 years old with one ARC port and a new Beam. The Anynet+ will not honour changing audio output when connected to the Beam via ARC. Bluetooth headphones? Connected for 3 seconds before the ARC connection resumes as the sound output and disconnects the headphones. Tested with all other audio connections, TV speaker, optical out, etc. with the same result. Turn off the Anynet+ CEC from Expert settings, all works as it should, but the Beam is no longer available as an audio output.
This is not an acceptable state of affairs, CEC is a very simple protocol that allows multiple input recognition, and support for BT headphones is as basic as changing channels. This needs a patch ASAP. The only workaround so far is to connect via optical and avoid the entire ARC ego tripping. Again headphone support is such a basic function, I am a little stunned that this was not addressed during testing! Otherwise, an excellent product, but Sonos really seems to have a thing hating on headphones!:P

Come on Sonos, you can't advice to "remove the cable from the Beam"... Come on
