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

Pathfinder

Had a response from Samsung

 

"Good morning Mr H*****, thank you for providing this update. I have requested any information available from our AV department on the soundbar software version and will return to advise where possible.

 

I will confirm with our service centre on availability for a weekend visit, as we are the manufacturer we work with a network of Samsung-trained service partners around the country, one of whom will attend"

 

I have stated weekends is my preference due to work commitments but will work from home if I have to. 

The start of the email is my questioning what the latest soundbar update is for.

I've done some more testing today to see if the problem is related to the way the surround is encoded - in short, it isnt !

 

I have done some test encodes at different bit rates and different dialnorm levels in both Dolby 5.1 and DTS 5.1 and while I can get the overall level to vary considerably the offset between front and rear when connected by WiFi remains consistent.

 

With the Soundbar and R1s set to the default "equal" level there is approx a 32dB offset - this is reduced to around 20dB when the soundbar is set to min and the R1s set to max.

 

The offset measures as volume independent - although subjectively it seems as if the surround speakers are louder the higher the overall volume - this is what I would expect.

 

However what I keep coming back to is the fact that the required volume setting for comfortable listening changed at the same time the surround was broken (and the WiFi connection issues fixed).

 

Prior to the problem my normal listening volume was in the mid 40s - now it is in the high teens to produce the same percieved volume.  My suspicion is that if we could have the rear speakers at say 45 and the soundbar at say 20 the front rearbalance would be correct - in other words the firmware change that dropped the overall volume on all channels should in fact only have dropped the soundbar volume and left the surround channels alone.

 

Interested to hear others thoughts on this...

Hi Simon,

Great testing albeit some of what you said went straight over my head.

Mine was the same that when they rolled out the fix for the wifi connectivity it screwed the sound, but what it also did was change the way the volume displayed and it's increments which may be where the problems lay (also first sound issues where muffled over bassy sound with low rear volume)

I forget exactly how it changed now its been so long and have detailed this on the the very first few pages; it used to only show a plus and minus sign on tv with numbers on soundbar I think, and then this changed to showing numbers on tv.

It also went from 1 to 100, to 1 to 50 increments.......... Which I think from memory changes also between 50 and 100 wifi/hdmi and optical inputs still

I may be wrong as haven't been looking for this specifically lately and may habe changed.

I suppose my point is that maybe it's the update very shortly after the wifi fix that caused the issues, as I certainly only noticed the muffled sound since the way the volume is displayed/incremented changed.

Hello,
Update done on the R3 (version 3112.5) and on the sound bar k650 (version 3111.2) and still no results in wifi on mode 5.1. The sound level of the sound bar is far too high. The sound level of the R3 is non-existent. When the equipment was purchased in December 2016, it worked perfectly. Why Samsung engineers are not able to go back on this earlier version if it was correct? It becomes scandalous !!!!
Sorry for the translation, but English is not my original language.
Go Samsung, find a solution now !!!

Hello,

 

It seems I'm having the same problems everybody is experiencing. Although I have a Samsung J7 series, a HW-J650 and 2 R3 speakers. I've tried a lot of connection options (Multiroom App, Sound Connect, Wifi, HDMI ARC, Optical...) and so far I have had (different) problems every time. Sync-Issues with TV, no real 5.1 instead mirrored front and rear, low volume on center or rears and so on. A quick test with the optical connection was giving the worst result for me in TV. A movie was televised in HD and Dolby and the Center volume was very low compared to the other speakers. Unvortunately I need to try all tests again with Blurays played on a PS4.

 

1) Reading through this thread, the US one and also other sites on the web I stumbled on something I need to clarify. In the Spec of the HW-J/K-650 for Audio Processing ther is given Dolby Digital 5.1ch and DTS 2ch. Does it mean, that DTS will output only Stereo Sound?

 

2) Does it make a difference where I connect my PS4 to, directly to TV or SB? I want a real 5.1 signal to reach the sound bar to know if every speaker is triggered indipendently.

 

3) Regarding 5.1 test material. I need to download some. But if I connect it via USB to the TV or PS4 will it be passed to the sound bar correctly. Or does the TV reduce it to a stero signal?

 

I am really sad about all the time I had to invest so far and not getting sufficient results. Hope that Samsung is working on this problem.

Yes this system is only 5.1 DD and 2.0 DTS. Shame that competitors can get the latest decoding standards and we are stuck with ones from 1995, but I knew that going in.

I had an interesting time last night. I had turned my TV and soundbar on and started playing my game and of course, the rears were super quiet (Wi-Fi multi channel). I go into the TV audio settings and the levels were at -6 and +6 as always, yet when I began lowering the rear level from +6, it suddenly got louder and then moving it back to +6 it was pretty loud. Did the same for the soundbar moving the audio up from -6 and then back down to -6 and it got quieter. It actually sounded balanced. Just strange that the settings were showing one thing, yet clearly it was not correct.

I'll do more testing later

Hi Angelo2002

 

1) Reading through this thread, the EU one and also other sites on the web I stumbled on something I need to clarify. In the Spec of the HW-J/K-650 for Audio Processing ther is given Dolby Digital 5.1ch and DTS 2ch. Does it mean, that DTS will output only Stereo Sound?

 

Yes - 5.1 Dolby and 2.1 DTS - not really an issue as there is very little DTS content available that doesnt also have a Dolby soundtrack in surround.

 

2) Does it make a difference where I connect my PS4 to, directly to TV or SB? I want a real 5.1 signal to reach the sound bar to know if every speaker is triggered indipendently.

 

Conect the PS4 to an HDMI in on the TV - the TV will pass the 5.1 through to the soundbar via optical (works) WiFi/HDMI ARC (dont work currently)

 

3) Regarding 5.1 test material. I need to download some. But if I connect it via USB to the TV or PS4 will it be passed to the sound bar correctly. Or does the TV reduce it to a stero signal?

 

Yes - 5.1 test material plays fine off a USB stick plugged into the TV as long it is a format the TV can play.  There is lots of 5.1 test material available from https://thedigitaltheater.com/index.php/dolby-trailers/

I  have just returned home after a short break and switched on the TV and soundbar.  The soundbar more or less immediately displayed that it was updating and I thought, just perhaps,  Samsung have fixed the issue.  However, for the record, I too can report  that there is no functional improvement in the sound delivered from the rears with my UE49KS8000KS,   HW-K650 and 2R1's when the connection between the TV and 5.1 soundbar+2R1's group is configured through WiFi, that compares at all with that available though the Optical or HDMI cable workaround.

 

Does any one know what this latest update did deliver?

Hi Simon,

 

Thank you for your reply!

 

Following up:

 

Dolby/DTS: I have found some Block Buster Blurays, e.g. Dr. Strange, that have only DTS audio tracks. This movie would be played as stereo on our setup, right? Would the rear speakers be silent, mirror the fronts or would some mixing happen? I remember watching The Avengers with DTS-track a few days ago. PS4 set to DTS and the Audio settings menu of the SamsungTV (for the soundbar I guess?) were Bitstream and DTS, if I recall correctly. The connection at that time was either Wifi or HDMI ARC. There was definitly coming good sound from the rears. And in combination with the Sound Bar it sounded good. But I could not distinguish if it was real 5.1.

 

optical connection: The optical was giving really bad sound for me in the last test with TV programm (HD movie but I do not remember what Audio format was passed). L/R/RL/RR were good. But I had almost no center (voice). I will however try it again with blurays and the audio formats from the link you gave.

Hi Angelo

 

It sounds as though you may not be running the latest firmware in your K650 soundbar - do you perhaps have auto update off ?

 

Some versions back there was an update to correct muffled sound issues and lack of centre channel.  This was followed by an update to fix WiFi connectivity issues. Unfortuantely one of these two also caused a massive drop in the signal sent to the surround speakers which is what we are all trying to get Samsung to fix.  Current version is 3111.2 for the K650 and 3112.5 for the R1s.

 

Most users in this forum are reporting that with an optical connection from TV to soundbar (and no HDMI-ARC connection), the soundbar set to D-in and the TV set to optical out, the surround performs as it should with the correct levels, quality and centre channel, but somethines not quite in sync with the picture.  The drop in rear channel level occurs when connected via HDMI-ARC or WiFi Multiroom.

 

Not sure what happens with a DTS disc - will have a look through my collection and see what I have to test with.  But I suspect that it will play as 3.1 or possibly "faux" 5.1 with the surround being synthesised by the soundbar, but not true discrete 5.1 - TBC
