When using the K650 sound bar and two R1 Wireless speakers in surround sound mode over wifi with the latest firmware, The quailty of the sound K650 drops, sounds very muddy. As soon as you use the sound bar on it own, the sound bar improves. this is happening for a quite a few users.

have you tried testing any 5.1 surround test videos

Next on my list but at least for now I can use all the speakers in surround mode. 


I just need to download a file and will post back

what TV do you have. do you have it setup with ARC and HDMI

TV is a UE65KU6000 


I have connected with optical lead from TV to soundbar (with no hdmi from TV to bar) 


Selected audio out/optical from the TV sound menu


Then grouped the speakers in surround mode through the app and not changed the tv


Then used the sound bar control to select   D.IN as the source

ok well let me know how the 5.1 test goes. 🙂

Search for lynnemusic and there are some surround files you can download for testing, including a 5.1 speaker test.

Thanks abob36

Ive tried a few downloads couldnt get it too work.

Once I get home from work I will try testing with optical out from my PC to see what's what.


In Netflix, search "test", click on the Netflix test pattern set and that has a sound test I beleive.

ok will give that a try,
