In most cases, this may be related to a compatibility issue with certain TV brands (LG / Sony / TCL / Roku / Vizio / Fire TV). You can try the following:

  • Set the TV’s “Digital Audio Output” to Dolby Atmos / Bitstream (not PCM).
  • Unplug and reconnect the eARC cable.
  • Restart the Soundbar.

If you have any questions, please contact our customer support team via email at support@ultimea.com, and we will assist you further.
