MU6400 and Q90R soundbar compatibility


I recently bought a Samsung Q90R 7.1.2 soundbar and have been trying to get it to work properly on my ue55mu6400 without much luck.

It connects up and sound comes through it, but I don't get proper 5.1.
I've tested with a. Few 5.1 YouTube videos (the ones where there is a visual of a 5.1 setup and each speaker is tested indivually).

Center left and right seem to work, the rears come from the front and the LFE test does nothing.

I have it connected with a hdmi 2.1 to the ARC ports. I've also tried optical and it's the same.

The pictures below show how I have the sound configured on the TV.

I would be very vary of using YouTube to test your speakers as they may well just be stereo. You are better off using test tones you can download. Search the dedicated forum for soundbars and you should find some..
