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.

Yeqh I was just messing about to see if it worked or not as a way to use the bluray player to decode Dts and pass it to the soundbar as PCM to get around the lack of Dts support but no joy. Lol
Scott if you set it to bitstream >>PCM you aren't getting a Dolby signal at all. It will sound "fuller" because rears will just copy L/R channel. Do you hear your rears all the time? In most tv shows rear channels aren't used much, so rear speakers are mostly silent or just playing occasional music/crickets :winking-face:


Check the link above for DTS 5.1 workaround if you have Android TV or Android TV box

PLEX can also transcode DTS to Dolby in real time. As for number of clicks, it's 8 to make a surround group, and 10-11 to disband and remake :winking-face: I can do it in less than 10s on a galaxy tab A 10.1

When I use that fraunhofer 5.1 test the rears do come on when fronts are playing and the rears also play rear channel audio. Not sure why.

When the bluray player is the source I dont get front channel audio from rears only rear channel audio when tv is set to bitstream pcm. 

 When I select bitstream dd when cable box is source it sounds muffled like there is something missing or a

compressed version of dolby digital.

Cable box audio selection shows auto detect dolby 5.1 whether bitstream dolby or bitstream pcm is selected on tv audio option. If I select pcm pcm on tv audio option cable box shows auto detect pcm 2.0


I don't see the point wasting time on such technical complexities as those mentioned above..Samsung have sold us a product that simply does not work - the fact we are discussing the set up in such details is ridiculous. I'm going back to John Lewis in 2 weeks when back in uk and showing them the almost 900 posts in this thread..I don't think we've put enough pressure on the suppliers who have a duty to sell us a functioning product just as much as Samsung???



I totally get what you are saying. I'm stuck with mine though so I'm just trying to get the best out of it for now. I'm pretty happy with the sound over optical. I still sometime get delayed audio. Just set my kodi to transpose DTS to DD and it works a treat.

I think limitations with DTS and lossless audio are fairly for the budget soundbar. And it's great that we can avoid it somehow for free.

But what I can't understand is why Samsung is not able to make couple of simple fixes for the best user experience.

I will try these 8 click manipulations, anyway, decent surround sound is still number one priority to me.


I am not genned-up on all the technicalities of Bitstream/ PCM /DTS 2 etc.  To re-appraise myself of the specs of the HWK650, I revisited its product description on   Now, I don't know if I missed it before or not but underneath the description of the 5.1 surround sound capabilites with Radiants, an asterixed comment states the "*Cable connection required from Soundbar to TV to receive 5.1 surround sound".  Is this an amendment Samsung  have made recently to this page?


I am pretty sure that I read somewhere that the cable connection was only required for non-Samsung TV's for wireless surround sound but was this referring to 3.1 surround sound only?


I dont have any cables between tv and soundbar and am getting 5.1 surround sound.
