Sonos Port Audio Out for Headphones While System Muted

I just installed a Sonos surround sound system for my TV HDMI ARC output -- Beam, Sub, two One SL’s, all brand new, latest generations. The TV puts out the HDMI ARC signal from several sources (cable box, Roku Ultra, Blu-ray player), all fed to it through an HDMI switch. It all works perfectly.

I want to add Bluetooth headphones for use when the speakers are otherwise silenced. If I install a Port, and feed the audio out to a Bluetooth transmitter, will the signal persist if the speakers are muted? Or is some other solution possible? If not, perhaps Port is not the answer, and then, what is?

The TV has optical out but works only when the signal is from the cable box. I’ve researched this with Aluratek, the maker of Bluetooth transmitter/receivers, and determined with them that this, while unfortunate, is expected. And the TV has no aux out.

Thank you.

I assume you are asking if you can mute the TV/Beam audio audio, but still have its audio play on your headphones - the answer to that is ‘Yes’.. you simply group the Beam with the Port and mute the Beam and the Port will output the TV audio via the line-out to your BT Transmitter, but note there is a slight delay with grouped audio of 75ms+ so you may experience some lip-sync issues with the video on the TV screen. I have tried this setup myself and I’m okay with the slight delay and hardly notice it, but I guess network conditions and distances can vary. I mostly use my headphone setup for music purposes anyway.

I had the BT aux only hooked up to a very old Marantz receiver. It worked when the receiver was set to AVR. With Sonos, no need for wired speakers, hence no need for receiver, hence the switch. All works. Port will enable use of the original transmitter, analog output.
