Q-Symphony not working with TV (QE75LS03TAUTK) and Soundbar (HW-Q70T)

Hello, I have been trying for months to get Q-Symphony to work with my TV, and it just doesn't work. I have tried almost everything. I tried connecting via HDMI, Wi-Fi to no avail. I don't know what to do. I tried factory resetting the TV and Soundbar and still doesn't work. I think it's because of an update (on the TV) that happened from version 22** to 23** and now even the latest update (2401) doesn't work. I do not have the optional rear surround speakers and I don't connect anything to the soundbar's HDMI port. Back then Q-Symphony worked with no problems using HDMI-eARC and using the included HDMI cable from the Soundbar but once after that update (on the TV) from 22** to 23**. It just stopped working. I thought maybe if I updated the Soundbar. It would work. I used the SmartThings app to check for updates on the Soundbar, and it said no updates available. I checked the support page and found an update and I got a USB OTG (Micro-USB to USB-A) and put the files on a 16 GB USB (formatted FAT32) and I did the update, and it worked on the Soundbar. I've got two devices with the latest update available, and it still doesn't work. I also decided maybe like it was region locked or something. I did an ISLS (Internet Service Location Setup) from Morocco to USA on the TV just to check and still nothing. I don't know what to do now. I mean yes I could shell out 150$ for the rear surround speakers (SWA-9100S) just why not, but I mean come on. The reason I want Q-Symphony is for surround sound. So basically from 3.1.2 to 5.1 channels and also If I do get the rear surround speakers. It will be theoretically a 7.1.2 channel setup obviously the speakers on the TV aren't exactly amazing but still. I really hope someone can help me and get this to work.

Let me make it easier for you, what exactly is the sound mode you have selected? Do you see TV + Soundbar option when yuy go to audio output settings? If you think the TV speaker sounds weak then you are not going to enjoy Qsymphony, it works well with Q95 series where the TV speakers are great too. One thing you might also notice Qsymphony is a bit consistent but greatly improved with Q90/95 models in 2022 and Soundbars like Q600 700 or 800 series.

No, I don't see a TV + Soundbar option well not anymore and I use all intelligent mode so everything is adaptive and yes I tried it. I disabled intelligent mode and put my soundbar to standard but still nope and for the models you listed. I don't have a 2022 tv nor soundbar. We talking Q-Symphony 1 not 2. I have a The Frame 2020 75" TV and HW-Q70T soundbar.

Does the soundbar have a remote? If so just restart soundbar, on your soundbar remote choose source and change it to D.IN

It should then allow you to choose TV +Soundbar

I said everything in the first post but yes I did already tried that. It didn't work and also tried turning on eARC and off and using just standard ARC but still nope. I do not have a toslink cable (Digital Input Cable).

I have the same problem on my frame (QN55LS03TAGXZS)
After many tests I turned off the Anynet+ and with this the TV speaker stayed on along with the sound bar.
The volume of each device is controlled separately.

Sorry my bad english.

I finally found something that just worked for me. While I was using a ps5, I tried to reset the soundbar by pressing the Config button (the one with the gear in it) by kinda 15 seconds until the soundbar says ok and turned off. After I turned on the soundbar, Q symphony config just pop up in my screen with all the info that is ready. To use I'm using a QN90CA 43 with a soundbar Q6C. Hope this work for someone :/.

Thank you for this comment! My Q-Symphony was not working and I held down the power button on my soundbar remote for 15 seconds and it turned off. Turned it back on and the Q-Symphony popped up. Thanks so much.

Unfortunately, no it hasn't for me since I have found out that it has been purposely disabled by Samsung starting from update 2401. I found out by entering the service menu (WHICH NOBODY SHOULD DO) and found the option for "Q-Symphony Support". It is set on 0. After I have set to 1 and quit the service menu by using a remote code on my phone "FACTORY" twice (to not reboot the TV) and then power cycled my soundbar and went into my options and found the option for TV + Soundbar. It connected and it worked and sure that may be a solution, but I found out the hard way that if you turn off your TV. it will power cycle and right after that option is gone and once I went back to the service menu well the Q-Symphony toggle was set to 0 and after I experimented around with the SW Model (DO NOT MESS AROUND WITH THIS OPTION AS IT IS POSSIBLE TO BRICK YOUR TV!) and selected on Q90T and there it showed Q-Symphony Support 1. I power cycled the TV and lost my frame features, etc... and guess what, Q-Symphony works. So, I have no idea why Samsung intentionally removed Q-Symphony support on The Frame 2020 models (LS03T) even though it is present in product manual, e-manual and website that it does support it. I found that they modified their article on supported Q-Symphony TV's, and I found that out using the internet archive and compared the page from 2021 and 2024 and right there it said TV's compatible: ... The Frame (LS03T) ...

So, I wish it was a bug but instead it was intentional. I wish Samsung would rectify this, but they probably won't since they are clearly discontinuing lots of the apps on the TV including some services.

Best regards.
