Samsung soundbar or wireless speakers have low max volume

The setting you're looking for is Digital Output Audio Format. On our newest TVs, this can be found at Home > Settings > Sound > Expert Settings. (It can also be found in the Quick Settings.)

If your Digital Output Audio Format isn't set to PCM, like for instance if you have a Dolby option selected, then you will likely notice decreased maximum volume. Dolby options are designed for surround systems (like 5.1 or 7.1), whereas PCM provides great sound quality for stereo speakers (2.1). (A number like 2.1 indicates 2 speakers and 1 subwoofer.)

If you don't have a surround system, you will probably want to select PCM. You'll get much louder volume that way, and potentially better sound quality.

1. Update the firmware on your soundbar to the latest version.
2. Turn off the soundbar when the update is completed.
3. Press and hold the Source button on the main unit for more than 5 seconds. If done correctly the soundbar will turn on.
4. The volume of the rear speakers will now match the volume of the front speakers when in surround mode.
