I pulled that youtube on my bluray player with wi-fi surround setup made by tv and couldnt get it to play correctly with any of the bluray players hdmi audio out settings. PCM, bitstream unprocessed or bitstream reencode dolby digital. Made the wi-fi surround setup with bluray player and it plays correctly.

Plays correctly from tv's youtube app with wi-fi surround setup by tv.

 

 Was just saying that I couldnt get it to play correctly through hdmi from bluray player to tv with tv wi-fi surround setup.

If you have dolby digital available as an audio format while that "lpcm" clip is playing then it is dolby digital not lpcm.

 

If it is dolby digital I dont understand why I cant play it from bluray players youtube app and send it to tv hdmi bitstream unprocessed.

OK Everyone - here is a test file to play with:

 

https://www.dropbox.com/s/1awk1cj45aksurq/Samsung%20Surround%20%26%20Sub%20Test.mp4?dl=0

 

Download the file - put it on a memory stick - and play it from the TVs USB slot.

 

It is encoded as Dolby Digital 5.1 and contains two sequences of pink noise.

 

In the first sequence the pink noise is sent only to the main channel and is not sent to the sub channel.

 

In the second sequence the pink noise is sent to both the main and sub channels.

 

On my system it is pretty clear what is going on.

 

In the first sequence the active crossover of the K650 is sending some signal to the sub from the front left and front right channels only but not the centre or the rears

 

In the second sequence the sub receives signal correctly for all channels.

 

What does this mean in practice?

 

Well, if the source is authored with a discrete sub channel created by the mix engineer the soundtrack will play correctly.  But if the source relies on sending full range signals to the 5 channels but no separate signal for the sub, only the front left and right will gain sub support, leaving the centre weak.

 

Is this a real world problem - well I think that members of this group have shown that it can be an issue on specific mixes but not everything.  I have yet to hear a problem on any of my DVDs or BluRays but in truth I havent been looking for it.

 

The fact that the MS650 apears to handle this better suggests to me that samsung are fully aware of the limitations of the K650...

Thanks Simon

 

I will give it a go.  So basically a real 5.1 track that has a discrete sub channel to compliment the other channels will.play fine. This might be why I haven't noticed a problem. All my movies are DD 5.1 or DTS with the exception of my new 4K blurays that are atmos. New soundbar in the future will be needed. I use kodi to transcode my DTS tracks to DD to get around the K650's lack of support.

Here is the easiest way for me to demonstrate the lack of sub support on the center channel.

 
If you have Netflix, search for a movie called “test pattern”. This movie plays a test sound from low to high through each of the five channels. If you place your hand on the subwoofer you will feel it vibrate while the sound is played on the left and right channels during the lows. But on the center channel you feel and hear nothing from the subwoofer during the lows. You would expect it should react the same way on the left, right AND center channels.
 
Can anyone else confirm if they can feel or hear sub support on the center channel while playing the same Test Pattern movie?

For me, in the first sequence, the K650 is sending some signal to the sub from the front left and front right channels only,  but not the centre or the rears.

 

Are you saying that K650 should not do this - there should be no sub for left & right channels?  Is this a defect that Samsung should fix? 

 

How would this fix my issue (my center channel is tinny on DD 5.1 movies)?  If Samsung removes the sub from left and right channel then surely this H650 would sound cr****er than now.   What is needed is for the sub to be active when the center plays.
