Just fitted a arc and 4 in ceiling Speakers as the surround, fitted both right to right and left to left, surround speakers are now set at +15 and are really quiet, watching fast and furious Hobbs and shaw on Netflix really poor? What have I done wrong?

Well that’s really strange.🤔

Your TV settings, from what you’ve said, seem correct, you’ve swapped cables, tried different Apps that show DD 5.1 audio, so it’s either the TV isn’t working as it should be, or its the Arc.

Can’t say I’ve ever seen this issue here on the forum previously.

My own thoughts, assuming you don’t have easy access to another TV to test the Arc, are to perhaps submit a Sonos diagnostic report, post it’s reference back here and then contact the Sonos Support Staff via this LINK to see if they can diagnose the issue. If not, then it might then be a case of speaking to LG Support who are on this phone number here in the U.K. 0344 847 5454

Could it be the amp?

You could maybe try ‘unbonding’ the Amp from the Arc, and perhaps any Sub too.. and then see what the Arc’s audio-output shows in the App.

These are my LG C9 TV Audio Settings too, FWIW…

Sound -> HDMI ARC: (Digital Sound Out = Pass-Through / eARC = ‘ON’)
Sound -> Additional Settings: (DTV Audio = Auto) / HDMI input format = Bitstream for all HDMI ports.
Connection -> HDMI Device Settings: (Auto Device Detection = ‘ON’ / Simplink = ‘ON’ / Auto Power Sync = ‘ON’)

It could also be the four speakers not matching the output/impedance of the amp.

Once you get the correct output from the TV to the Arc, of course.

Sonos amp and 4 Sonos in ceiling speakers, it has to be compatible.

What was the audo-in displaying after unbonding the surrounds from the Arc?

Sonos doesn’t make in ceiling speakers, do you mean the Sonance Architectural series of ceiling speakers? Sonos does sell them through the website, due to a marketing agreement with Sonance. But if they aren’t the Architectural series, they may not work as you expect. Once GuitarSuperstar and Ken get you to a point where your TV is passing the correct signal to the Amp, that is.

Thanks for everyone’s help, I’ve reset the TV, the arc, the amp the lot, I have another set up in a different room using a Sonos playbar and it all works fine, don’t understand what the problem is?
