I also have a question about this: I have freshly installed the Sonis Beam TV Box 5. Now I can no longer turn the beam louder and quieter using the remote control, but the volume control appears on the left side of the TV, otherwise it always came via home theater volume… I’ve tried everything. I don’t know what to do next. Is it related to the new Sonos update? 
I have the same thing with my soundbar. I have now installed it or moved it as my colleague suggested, but now after starting the TV box the volume control comes via the TV box instead of the soundbar 😞 every time I turn the box on again the setting is no longer working. I’ve had Swisscom for a few days now and I’m already getting desperate when I have to change it every day. because when I turn it down it’s always at 50 or max. and only when I get to 3 does it actually become quieter…
Of course, the settings of the TV-Box 5 should not be lost during a restart, but since almost no one operates a TV-Box on a switchable power strip or similar due to the very long cold start time, it cannot be ruled out that sometimes not everything works perfectly.
At least as a test, I would switch to standby mode and then check whether all the problems might go away.

@Werner I have it in standby and when I start the TV box, the volume control is back on the box and not on the soundbar. To do this, you have to uncheck the volume box under the settings and under HDMI CEC and then put it back in again. then it works. But as soon as I turn the TV etc off (always standby) and then turn it on again, the volume only works on the box and not on the soundbar.
I’ve now tried everything I can with settings, including my 7-year-old TV and the 3-year-old soundbar.
In this thread, various problems were discussed in parallel, which makes the overview a little difficult.
But assuming you have now wired everything via HDMI via the TV as a central hub:
Take out the HDMI-CEC volume synchronization on the Swisscom TV-Box and limit yourself to the one-remote function on the TV-Box (this means that the volume of the TV is then controlled directly with the SC remote control via infrared on the TV) and from It should, or at least could, be passed on to the soundbar.

Hello @P_koller
What have you set in Settings => Video and Audio => Audio and Sound? Is there surround in there?
I’ve now tested this on myself. The setting stays saved for me. So it doesn’t seem to be a general problem.
I can’t say whether you got the Monday box. Whether a hard reset changes anything, I have no idea.
Edit, the tip from @Werner in the posting directly before mine might be worth another try.
And otherwise just switch off the soundbar manually using its FB.
as a current short update:
I have now reset my TV box to factory settings and the sound setting remains the same for the last time it was turned on/off. All devices are also switched on and off.
The box probably “fired” or disconnected during commissioning.
Hope it stays that way.
Thank you all for the tips and support so far.
Hello Werner
Sorry, I have to jump in here, today I bought my TV OLED77C4 from LG and the soundbar from LG DSG10TY
So I have to plug the Swisscombox directly into HDMI 1 and then connect the TV eARC to the soundbar eARC connection.
Correctly?
Until now I had HDMI CABLE to the soundbar HDMI IN and then Sound eARC to TV eARC.
Which settings do I still have to adjust?
Thank you very much
