Smart TV external speakers sound distorted
4.5
Audio sent to external speakers has static, pops, or is out of sync.
Symptoms
- Popping sounds
- Audio delay
- Static noise
Possible Causes
- Digital format mismatch
- Bad cable
- Ground loop interference
Step-by-Step Fix
1
Change Audio Format
Switch the TV output from "Auto" or "Dolby" to "PCM" to see if distortion stops.
2
Replace Cable
A frayed HDMI or Optical cable can cause digital "jitter" or noise.
3
Check Grounding
Ensure the TV and soundbar are plugged into the same power strip.
When to See a Technician
If the sound is only distorted on high-bitrate content (4K), your HDMI cable may not have enough bandwidth.
