HW-K650 and Two R1 Wirelss Speakers in 5.1 With KS7000 TV


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 will hard reset everthing this evening when I get home from work and do some more testing. More concerning for me was that this morning when I tried it out with the new TV update is that the TV was losinf connection to the sounbar and rears. Also there was a small buzz everytime I turned the volume up and down. If I have to revert to the optical work around its no big deal as long as its sorted in the long run.



I think the Sony system only does 5.1 if connected via optical cable, though I may be wrong. It does have two HD inputs and one arc HD output too though, so you have the option of routing your video through the Blueray player/basestation, instead of routing it through the television. Personally, I use an optical splitter on it, and connect the hd direct to the tv.

It may not have the tv wireless functionality you're looking for (though it has a lot of functioanlity), but it's wireless rear speakers are dedicated for that job (as opposed to what is becoming more apparent with the R1s etc, as retrofitted to being rear speakers). And because it's not a soundbar (its an actual 5.1 speaker system), there is a better front soundstage. 

The main reason I took my k650 back though was the diverging firmware issue, which is likely to continue in the future (one item will stop having its firmware supported before the other...).

The Sony may end up with bad firmware too, but as its effectively a "home theatre in a box", I assume/hope the firmware would be quicker to rectify/ much less likely to be released broken in the first place. There are also reports of some speakers going bad and becoming distorted, but Sony will replace under warranty. Much easier to gain support for a broken hardware, than a harder to prove broken firmware...

I've not had these tv connectivity issues - my biggest worry is that we will lose momentum and end up settling for the work around which is not acceptable. It would be nice if the community manager was a bit more active and kept us updated i.e. whether he's acknowledged there are now issues with the rears. If not my next step will be writing to consumer protection because this is ridiculous.

Hi Robbienobs


We still very much have eyes on this thread.  I have sent over the recent feedback and will send a follow-up on Monday.


In the meantime, please do keep the feedback coming.



Thanks LeeS great to know you are reading these Im sure we will get there in the end!

Thanks LeeS



So, I have just finished doing a hard reset on the soundbar, surrounds and TV. solve my connection problem but still hardly any sound from the rear channels until you turn the sound right up. back to optical.and thankfully that's working ok still. all we need is more volume on the rear channels please.  



Just to confirm I am on tv firmware 1154 and have not had any recent updates. 


TV is UE65KU6000 


not so sure if its the tv firmware causing issues as I am on an older version to others I think. 


Anyone else on 1154?

So you are having problems on the old firmware? mine was OK until the TV updated. 

Yes on 1154 with low to no volume on rears in full wifi. Fine on optical workaround. 


Can't be a firmware issue on tv in my opinion
