LG SL4Y + SPK8-S Sound issue


Active Member
Hi guys

I have recently bought an LG SL4Y & Rear speaker kit SPK8 the rear speakers connect and work but it seems to be the same sound coming out of all speakers and soundbar so you have someone speaking through all speakers instead of just rears having ambient sound is this correct?

I’ve tested with Apple TV and Netflix, Disney plus and it would seem i can hear the same through soundbar and same on the rear speakers.

Tv is LG UM7100PLB and it’s connected to soundbar via optical cable

Just in case anyone else has a problem where dialogue is coming from all speakers or rear speakers not working with 5.1 or

I disabled LG Sound Sync in settings (this lets you see volume control on tv rather than soundbar) then put Digital Sound Output too Auto

Now when watching content with 5.1 the rears act as they should.
