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.

I got this quick email reply from A1TV... 


"Hi  M5 will be software for your rear speakers

Kind Regards"



Good news! 


Hopefully fix is final and doesn't cause consequencial issues as before


Frankly, I have completely given up. Really don't see how the R1s can be anything other than wifi. No connections are available on the speakers. I on a couple of different attemts have got the rear speakers to work with the bar, but practically no volume.  Other times it doesn't work at all and when I turn the tv on I don't even get the option to choose the bar with surround in the sound settings of the tv.


I agree that the radiant speakers sound good when playing tunes thru them (I have a total of eight), but sometimes they get very hicupy.  I thougt maybe it was a bandwidth issue.  Have increased FIOS internet to 100/100, have added a network extender, and a samsung hub that the speakers all go thru.  Still have intermittent problems.  


Anyone that has dealt with Samsung Tech Support knows it sucks.  I also now know their warranty sucks as well.  I'm having an issure with a 65" 8000 series tv that is four months old and has two vertical discolored 4" wide bands running thru the panel.  They tell me that it's normal they all do it!!!!  *****


Hi all. Just wanted to throw my hat in the ring with reference to the problem of low volume from the rear speakers. I too I have just spent £3000.00 on this system (KS8000, HWK650 and two R7's) along with blue ray player. I too have spent an age getting this kit to work but to no avail. Can you reassure me that a software update is inevitable (so I can save my marriage!!) to enable the volume of the rear speakers to produce the sort of sound expected from a surround sytem?


I solved my problem by linking the optical cable to my tv and choose it for the audio source. Then just connect the surround system in the multiroom app. It wont work less all of your speakers are connected to a good and solid wifi-network, couse the system still uses the wifi to connect the speakers with each other. 


After one month of problems and the Swedish support line blaiming my router and the walls of my house... Well, now I'm just happy it works.


Thanks for the idea with the optical cable. The support never though of this. 


Great. Thanks for that I will try it tomorrow. Question. Do you now get good sound from your rear speakers applying this method?

I'm not a sound expert and really don't know what to expect, but yes I think so. I balanced it a bit by taking down the volume a bit for the soundbar, and I raised it a bit for the other speakers. 



So here is my update. Upon purchasing a high quality optical cable and connecting soundbar to Tv removing the HDMI cable (recreating the "bodge") in essence it would appear that there is no difference in the sound quality to the R7's as opposed to the HDMI from soundbar to TV and setting up the surround via the multiroom app. So it doesn't work. I have resigned myself to the fact that i must indeed wait patiently while Samsung stop sitting on their hands and actually give all us loyal Samsung users who have spent hard earned cash £3000.00 a satisfactory and complete solution to this problem. I am fed up...sigh #shouldofstuckwithmyoldsetup.


I have just tried exactly the same thing without success. 


My 55KS7000 is set to Audio Format Dolby Digital, I have an optical link between the TV and soundbar.

I have disconnected the HDMI ARC lead to the soundbar. (WIFI is still available).

I set the TV to use optical out and the soundbar recognises it as mult channel sound. 


I have grouped my HWK-650 & two R1s using the android app. The test works OK, but there is still no sound output from the rear when playing a 5.1 source (I used Netflix).


Is there anything that I am doing wrong? 


Can someone that has this working please let me know what settings they have on the TV under the Sound heading.




I have excatly the same setup as you and it works with Netflix but I still have the hdmi cable connected to the arc channel,



hdmi audio = bitstream

audio format = Dolby digital
