major problem with Sonos Arc Ultra - Sonos doesn't let switch to other speakers from TV menu

I’m raising this issue yet again.   I can confirm that that Sonos Arc Ultra displays the same issue with the very latest LG C5 TV.   So this problem is not confined to some older TV’s or some small subset of manufacturers.  Sonos seems to be intent on completely refusing and ignoring the problem.  This is a bug.  When is Sonos planning to fix this?

 

Once you have Sonos Arc connected through HDMI ARC connection, you can no longer use built-in TV menu to route the sound to whatever output you want - be it internal TV speakers, headphones connected to TV or anything else.  After a few seconds the sound is again routed to Sonos.  I have previously confirmed on Samsung TV, that this was not a problem with the Samsung soundbar or Sennheiser sound bar.

I already raised it previously reporting it for other TV model and it was closed:

Below are two of my LG sets both are connected to Arc Ultra’s. The 1st being an OLED and the 2nd a NANO which is LG technology just below OLED but more than normal LED. Not that you need to know those particulars.

Suffice it to say that when I turn Simp-link (CEC) off the sound switches to internal speakers. Just for added measure I manually select internal speakers.

The bottom-line is that the internal speakers remain on and do not switch back the Arc Ultra’s. Therefore, assuming the OP is doing everything correctly their issue is related to how CEC is implemented on their LG.

A call to LG is warranted. Although LG may deny that there exists an issue and place blame on Sonos. C’est la vie!

It’s not about the TV, it’s about being able to switch to Bluetooth headphones at nighttime when everyone’s sleeping. I shouldn’t need to buy Sonos headphones to use my Bluetooth headphones on my tv and be forced to unplug my Sonos beam 2 every single time wearing down the hdmi prongs and/or power supply internals. It’s ridiculous. 
 

it’s a simple fix, just let us POWER DOWN the soundbar via the app, so freakin simple.

 

So what’s the difference between using the app to power down the soundbar, and using a remote to turn off CEC on the TV?

I have the exact same issue with my Samsung S90D 77”. Sometimes I am trying to change to the TV speakers but a few seconds later the settings will jump back to Sonos system.

Not sure what the purpose of this last post is. From the rest of this thread (and a couple of older threads) it is clear Sonos has had this feature for years and they are not changing it.

I can see this could a problem if you want to use non-Sonos headphones - though turning off CEC or buying a Sonos Ace resolves this. But I cannot not for the life of me understand why so many people buy an expensive soundbar and decide to not use it all the time.

 I know which TV to get now.  A new LG.  My Sony occasionally fails the HDMI handshake which forces me to reboot the TV.  Fortunately that can be done using the Sony remote.  Sounds like the LG would not have that handshake issue.

 I think dintis has the right idea suggesting there may be a way to disrupt the HDMI handshake from the Sonos app.  Not sure this would work though when the TV is LG.  We have an LG in the master bedroom.  I was trying to use Amazon Echo speakers as the sound source for the LG TV.  I worked well, but one of the Echo speakers was having other issues related to notifications.  So I removed them from the LG TV.  As I recall the LG did not automatically switch to the internal TV speakers.  I had to go into the LG menu to switch to TV speakers.  Using a Beam on that TV now.  So it may also be necessary to manually switch the LG to Bluetooth to get that to work.  I’ve never tried Bluetooth on the LG.

 Bluetooth on my large Sony TV requires me to use the Sony remote to pair with headphones.  Is that not possible when using an LG TV?

One button press, versus going deep into TV menu hierarchy using who knows how many clicks.  Last time, I did it, I forgot about and suddenly couldn’t output the sound to Sonos at all, as when the HDMI CEC is shut down, you will NOT be able to play sound through the Sonos soundbar.   I though the firmware update has broken it, spent a huge of amount of time troubleshooting it, until discovering that the option was indeed turned off deep inside the menu.  It is a stupid workaround for the problem that shoudn’t be there.

Sonos has the same problem with the LG.
