My Q80T tv keeps loosing connection to my Q800T soundbar.

Sound output no longer shows [AV] Soundbar Q800T(HDMI)

Toggling HDMI-eARC Mode doesn't fix it. Toggling Anynet+ (HDMI-CEC) doesn't fix it. 

Only way to fix it is to unplug both for 10 mins (not sure what the correct time is but 10 minds work). Then when I turn both on I get the "Dolby atmos enabled device connected" (or something like that) notification. 

Is it the TV or soundbar that's the issue? This is getting old. I don't have issues with my old TV (super old Samsung) and soundbar (N450).

Hello! I understand how this can be frustrating with this occurring with your soundbar have you had a chance to try the troubleshooting steps below?


Each model has a firmware update on Samsung.com to correct the issue. Please confirm your model and then follow the steps to update the firmware:

  • HW-Q600A : Version with the issue - 1000.9 / 0068  New version - 1001.1 or later / 0071 or later.
  • HW-A650: Version with the issue - 1001.0. New version - 1002.2 or later.
  • HW-T650: Version with the issue - 1003.6. New version - 1005.3 or later.

HW-Q600A has two firmware files that need to be installed. You can download both from Samsung.com. It does not matter which order they are installed, but you must install both and they must be placed on the USB one at a time.

    1. On your computer, navigate to the download center on Samsung.com

      Have a USB Drive handy, and go to samsung.com/us/support/downloads. Select TVS & Home Theaters > Home Theaters > Soundbars. Then select Q Series if you have the HW-Q600AA Series if you have the HW-A650, or T Series if you have the HW-T650. Then select your model.

    2. Download the latest version of the firmware.

      The latest version of the firmware will include the fix for this issue. Download the firmware for your model.

      firmware for Q600A

Don't forgot to download both firmware files listed for the Q600A.

    1. Unzip the file and place the contents on the root of the USB thumb drive.

      Place the contents of the unzipped firmware folder on the USB drive without placing it any folders.

For the Q600A, you can do either firmware file first, but you need to do each separately. Make a note of the file you install first, so you can come back to install the next file after the first is completed.

    1. Insert the USB drive into the USB port of the soundbar.

    2. Turn on the soundbar and change the source to USB.

    3. Firmware will install automatically and the soundbar will restart when complete.

If you have a Q600A, go back to Step 3 and repeat the steps with the other firmware file.
