Samsung Soundbar loses audio/video sync or disconnects when connected via HDMI ARC

out of sync ARC

If you notice that your Q600A, A650, or T650 soundbar is out of sync with your TV or randomly disconnects when connected via HDMI ARC, there is a simple solution to correct this issue. 

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-Q600A, A 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.

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

  3. 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.

    4. 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.

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

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

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

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