Hi All, going crazy here. New sohndbar all hooked up and everything seemed fine until the TV creates an echo as the Q symphony is out of sync between the soundbar and TV. Only happens with certain front/left front/right channels are being used. Horrible sound experience and I cannot seem to fix it. Any ideas? Both connected via eARC and if I select soundbar  problem goes away. Seems a real issue between 2 Samsung products that fail to deliver on  a key selling feature.

HEY @Jim-Jam 
I did some more research and was told the following: It is probably not advisable to use the Q-Symphony and rear speakers at the same time, since the Q-Symphony has the same effect as the rear speakers. This can give the impression of an echo because the tones are mixed incorrectly.

Interesting - that seems weird, though, considering Samsung advertises the TV with 'wireless Dolby Atmos' and the Q-Symphony function along with the Soundbar (with the rear speakers) being Q-Symphony-ready as well.

What did they say about the 'same effect as the rear speakers'? Because that doesn't really make sense to me. My understanding is that the speakers on the TV are up-firing in the front to create some of the overhead sounds and working in tandem with the rear speakers that are doing the 'typical' surround sound functionality.

And I'd be curious about the 'impression of an echo' because it seems to be solvable with the audio delay settings (just in a way that messes up the audio/video sync), meaning it's not just tones overlapping to sound like an echo - it's literally the sound information being played at a time offset to the main signal.

Hey @Jim-Jam 
I thought the same too! The echo is no longer my primary problem - I just got that under control with the synchronization. I compared some scenes - and believe me I compared them often! Once with Q-Symphony and once without! I think everything is overdriven with Q-Symohony and the rears remain partially silent because the signal that should actually go to the rears is reproduced by the tv.

I also found this: 
https://eu.community.samsung.com/t5/audio-video/swa-9500s-rear-speakers-q-symphony/td-p/5771367

Q-Symphony does exactly what the REARS should do. I'm a bit angry myself because I preferred a Sony TV with Dolby Vision to the Samsung TV because of the Q-Symphony function. the Sony would also have been cheaper by 200€ 😑
Well, the soundbar sounds great even without the function, or better! 😎

I hear ya - from that link you posted:

By now you must have noticed that Samsung sells soundbars that already include rear speakers and advertise them as Q-Symphony compatible.

That's my main issue here. The soundbar that includes rear speakers show them as having Q-Symphony compatibility as does the TV.

I'm hoping that the Samsung engineers look into it, because having all of these issues for an advertised feature is really not cool.

I'll let you know if I hear back. My post is here: https://us.community.samsung.com/t5/Home-Theater/Q-Symphony-Out-of-Sync-with-Atmos-Content-on-S95B-a...

Hi,

I recently bought a q700c soundbar to my qn85b tv and it had of course exactly the same echo-problem while playing dolby atmos with q-symphony. I updated the soundbar to version 1004 (the update was possible only with usb-stick). The echo was a bit better but still there. I then played with the digital output audio delay (TV) and audio sync (soundbar) and when I put the TV at 170-180ms and the soundbar at 0ms the echo was gone. I tested it on several movies on deferent apps with and without dolby atmos and I never heard an echo. The video-audio is also in a good sync. I hope that helps.

chears!

Agreed. This is junk. And it’s still the same in 2024. Support is useless. It does not work. Some content it will. Others it won’t. It’s poor.
