Subject: Intermittent Audio Dropouts When Using HDMI

Definition:

Audio dropout: Occurs when the audio portion of a program temporarily stops and starts again. Can range from a few seconds to several minutes.

Possible Causes:

Weak Signal

Set-Top-Boxes (STBs) might lose transmitted signals due to a weak signal, leading to audio dropouts.

Solution: Contact your cable/satellite provider for better signal strength or replace old cable wiring and splitters.

HDMI Handshake Sync Issues

The HDMI connection occasionally undergoes HDCP (High-Bandwidth Digital Content Protection) verification to ensure received content is secure.

This process can sometimes cause audio dropouts.

Solution: Test the HDMI connection with another device. If the issue persists, consider upgrading your equipment or contacting your provider for new equipment or firmware updates.

Faulty HDMI Cables

Audio dropouts can result from damaged HDMI cables.

Solution: Connect a different device to the cable to test its functionality. Replace the cable if necessary.

Defective HDMI Ports or Circuitry

A faulty HDMI port might lead to audio dropouts.

Solution: Try connecting your device to a different HDMI port on the TV. If the issue stops, the original port is likely defective and requires servicing.
