Sonos Beam and Bose QC headphones in Samsung TV

I’m having the same issue. Tried to turn off TV autoplay in the Sonos app, but this didn’t help. It’s definitely a software issue.

Here is the DM I got, for the record:

“The Beam is designed to always take audio priority when connected to your TV via an HDMI-ARC connection. The workaround of toggling Anynet off and on would likely be the best approach. Alternatively removing the HDMI connection from your Beam while using an alternative audio source should also prevent that behavior.”

I suppose since I'm in the menus to change the audio output to headphones, I may as well turn off AnyNet+ too... annoying, yes, but I suppose it'll work. I still consider this to be a bug though, and that's just a workaround, IMHO.

Exact same issue here:

Samsung QE55Q8CAM
Sonos Beam via HDMI-ARC port
Parrot Zik V1.10 Headphones and Bose SoundSport Wireless Earphones

Same issue here:
Samsung UE40MU6100
Sonos Beam via HDMI-ARC port
Tested with three headphones: Jabra Halo 2, JBL and Sony
This tv also has optical out. When the Beam is connected via Optical out, the Bluetooth connection remains stable. However, this is not the way I was hoping to use the Beam, because sometimes the internal speaker of the tv wants to add it's voice.
Most annoying to watch in the settings is the Samsung feature to have multiple audio output to internal speakers and Bluetooth, bus this option is greyed out when Anynet is on.

I have a LG OLED TV and have same issue - I use headphones quite a lot, and it is disturbing that someone thinks you that it is ok and designed well, that Beam completely disables possibility to listens TV with bluetooth headphones and recommends you to to disconnect HDMI every time you want to use headphones instead of Beam. I would be ok with it, if Beam had ability to connect bluetooth headphones, but otherwise ???

Thanks for the reports, everyone. We've been looking into this issue. It's caused by the way the TV handles a command the Beam sends as part of the process to issue CEC commands to the TV like "off" and "on".

I'll make sure to let the team know you're running into this and that it's causing you trouble. For now, the best solutions are to turn off CEC when you're using the headphones, or if you use them frequently, it may be to use the optical output instead of the HDMI. You'd lose the CEC controls from the Beam, but if you use the headphones a lot this may be worth it.

I'll pass along this as a request too for the future.

Hi Ryan, very happy to hear you are looking into this and will be looking to fix it.

Can you please advise what functionality we will lose by using the optical adapter? It seems like the way I’ll need to go for now.

Just tried it - remote no longer controls volume on the beam so obviously that is way worse. Back to hdmi and plugging / unplugging the cable until there is a fix.

If your remote has the option to output IR, you can set it up in the Beam's settings > Room Settings which would work for remote control. The only functions you should lose with the optical are the CEC ones, being able to issue commands to the TV from the Beam.
