Intermittent or Poor Audio (From External Device)

Symptoms:

• Audio drops or distorts when using HDMI ARC or Optical connection

• Delay or static when switching inputs

Steps to Resolve:

1. Replace HDMI or Optical Cable – damaged or low-quality cables can cause dropouts.

2. Power Cycle both the TV and external device (soundbar/receiver).

3. Disable Audio Sync / Lip Sync Features if available.

4. Update the Firmware on the soundbar or receiver (check manufacturer website).

5. If the sound still cuts out, test the soundbar on another TV to isolate the fault.
