Flatpanels also experienced what I did regarding 2.0 upmixing and which Geoff has confirmed a fix is in the works for:

Initially, my experiences with the distinct center channel caused some confusion when the sound source signal switched from multi-channel to simple stereo, which is typical in news broadcasts, older series, and documentaries. Suddenly, the sound was too sharp, without any bass, and while the dialog on film tracks was precise, it was very similar to what one would expect from a dedicated surround center channel. It sounded more like a single tweeter without any bass. Fortunately, Bang & Olufsen confirmed that 2.0 PCM was unfortunately not upmixed to match Theatre's many speakers correctly, so the temporary solution was to turn off upmixing and let Theatre play 1:1 – and thus not take advantage of the many extra speakers. This is a known issue, and B&O is working on rolling out a fix, but at the end of this test, the update had not yet been released. Unfortunately, turning off upmixing is a general setting that cannot be controlled in a dedicated sound profile, so we look forward to a more permanent solution.

Same, and I think this issue explains why even Andrew Robinson's review mentioned that puzzlingly, while movies etc sounded great, some regular tv sounded odd and even like a cheap sound bar.

My bedroom theatre particularly, where there are no other speaker attached, sounds poor / wrong / bad when the signal switches to 2.0 PCM.

While adjusting in the app to a sound mode with Direct 1:1 processing is not the end of the world, its also something we shouldn't have to do for the simple task of watching TV.

I dont notice the issue for my living room Theatre setup, which has loads of other speakers attached to the Theatre.

But long story short, this needs fixing soon.

My BST was updated a couple of days ago (the SW was pushed).

As of today - when opening the app - I was told the it had been regularly/automatic updated……to the same version ?

Anyway…..this time the new features/news were stated in the app (I made a screenshop just in case that could not be found again later on).
Only the new features are listed - no talk of bug fixes.

I can’t say whether the issue with the tiny sound from tv (tuner in LG) was fixed, since I generally do not use the BST on it’s own.
I made a test playing from tv with only BST - that sounded ok to me.
I guess testing on an only BST setup and with the new SW will be needed (@Sandyb).

This is how it looks in my case, when playing from the LG tuner/DVB-T.
This might be different for other users.

By the way…….changing from eARC to ARC in the LG settings made a difference in the perceived sound on the Theatre alone.
Since I only use the tuner of the LG and no apps, I have mine in the ARC setting now.
Would be nice to hear about this from others.

 

P.S. After the update I have a ‘new issue’.
Testing around I noticed that - when returning from a multi speaker ‘group’ to the BST alone - it takes up to 7 seconds to get sound.
The other way ‘round sound is immediately there.
Not a problem in our daily use cases, but weird anyway.

Also - just in case you experience this - I had crackling noices from the BST after updating.
A reboot (through the app) solved this.

Is this a beta or public release?

My BL28 received an auto update but the TH didn't show an updated 2.5.3 of the beta, they differ a few build numbers now. I'll check again later today. Also could not connect through airplay anymore, wondering if that's due to the Release Candidate from apple or the beta of B&O

Hi there MM

On one of the recent podcast the lag when changing listening positions was discussed. It seems that there are some who have long-ish lags (similar to yours), and those for whom the lag is more or less not there i.e. 1-2 seconds.

I've played around with my experience - and flicking between LP's, my lag is between 1-2 seconds. No idea why some have this 7 second lag - Michael, the podcast host, has always had 7 second lags since his Theatre was installed.

The lag is distinctly longer when a listening position includes more or less speakers than the active position.

for example

when I do a sweet spot change with BS TH + BL28 set in narrow to wide it’s nearly instant.
when I change the position from BS TH + BL28 to an position where a set of BL17’s are added there is a few second lag.
my guess is that the BS TH needs to process the soundsignal to split in more channels and needs time to do so…

same when switching from a music position with the BL28 alone and a position with BL28 + BL19 btw

With respect to time lags when switching LPs

I can switch between LPs including the theatre, and LPs with no theatre....and going back and forward between these inc and ex Theatre LPs, it's still a fraction under 2 seconds.

 

Thanks for the feedback. Good to know. Might it be a WiFi thing then? Or wisa actually?

ate your speakers hard wired?

@Mikipedia is one of the few people with many speakers fulfilling several roles.  @Sandyb has just the two speakers and the Theatre.  Speculation: Perhaps when switching listening positions, the Theatre cycles thru each speaker, powering it up -- and instead of accumulating/max-ing the wait times of all speakers before their amplifiers click on, it performs the delay per speaker (or pair) serially?  After moving, when he sets it up again, maybe @Mikipedia can try with only one pair of external speakers...
