On the BV7 speaker group for 'TV', can't you just activate all speakers?  That's all I've done on mine for TV use.  For my music group I deactivate the centre BL7.4 as it sounds terrible with music.  For film, I have everthing on.  

Do you have AST on or off?

Dave.

If Viaplay offers only stereo sound, you cannot make it into 5.1.

Even if you force the BV7 to distribute to all speakers, they sound will sound strange. 

I do suspect that your setup is already sending the stereo sound as a 5.1, and that is why you are not satisfied with the sound.

Add "speakers" to your Beo4, and press 2 to check if the sound is diffent. Then chose 5 again to compare.

All speakers are activated for video input, but for stereo music, just the front speakers. (Totally agree about the sound of music!)

In general, Playstation 4 handles 5.1 sound just fine. All channels are open and active. It's just the Viaplay streaming application that fills the left and right front speakers with sound, but leaves the center and back speakers with nothing.

Where is the AST (Adaptive Surround Technology) setting?

Menu, options, sound.  Under the sound settings, it's the bottom parameter.  This may depend on BV7 type and MK?

Have you also tried the Viaplay support website?

Users with Netflix have a similar issue which is solved by opening the 'audio' bubble as it seems to be called and changing the audio options. Possibly there is something similar with Viaplay but I've never heard of it before so can't tell you where it is..

Playing a 2.0 signal through all speakers/through a 5.1 setup is called 'upmixing'.

Some like it - some don't!

Some upmixers do a good job, others a not so good!

Personally I would not let a BV7 (which MK are we talking, by the way) do such upmixing.

What the new audioengine (in BSys4 based systems) can do, is different - and might be more pleasing.

If the sound source from a video is 2.0, I would - on a BV7 - (manually) choose the default B&O 3.0/3.1 version for it - aka Speaker 3.

Thank you, Dave and leosgonewild, I'll try this out when I get home. Yes, the problem is really within Viaplay. I found nothing in their support pages, but I have contacted them, waiting for answer. Perhaps the most promising option now is to try out speaker combinations, although I fear that I'll be left with the choice between center only and front only, as the center will be silenced when I add front speakers.

What centre speaker do you have?  

Dave.

Thank you, Millenissen, for the word - upmixing. While not optimal, the current alternative with the center speaker silent is worse. It sounds like if the walls are speaking, not the persons on the screen. Your choice of Speaker 3 would probably leave the center speaker quiet, the same. Technically the sound input is 5.1, only that the center and back speakers are fed with the sound of silence! Another way to ask, how can BV7 ignore input from center and back and distribute left and right front channels over 3.1 or 5.1, whatever? The source of the problem is a misfit between Viaplay and PS4, and I doubt BV7 has a good workaround.

The BV7 is MK-V.
