Troubleshooting Single Speaker Dropouts in a SoundSend System

If you are watching a movie and one ceiling speaker suddenly stops producing sound while the other speakers continue playing normally, this is typically related to an audio format or eARC communication issue between the TV and the SoundSend system.

In many cases, the speaker may temporarily start working again after switching inputs or restarting playback.

Common Cause

This issue is often caused by:

• Audio stream decoding confusion
• TV eARC setting conflicts
• Dynamic format switching between content types

For example:

• Switching from a stereo YouTube video
  to
• A Dolby Atmos or Dolby Digital Plus movie

can sometimes cause certain TVs to mishandle audio channel assignments.

Recommended Fix

Adjust the TV eARC Setting

1. Open your TV:

   Settings

2. Navigate to:

   Audio Settings

3. Locate:

   eARC Mode

4. If eARC is currently set to:

   ON

   change it to:

   Auto

Why This Helps

Some televisions can experience audio dropouts or channel loss when eARC is forced permanently ON, especially when content changes between:

• Stereo
• Dolby Digital
• Dolby Digital Plus
• Dolby Atmos

Setting eARC to:

Auto

allows the TV to negotiate the correct audio format dynamically and can prevent individual speaker dropouts.

Additional Tips

If the issue continues:

• Power cycle the TV and SoundSend system
• Ensure your HDMI cable supports eARC/ARC
• Update your TV firmware
• Verify the source device audio output settings
• Avoid forcing unsupported audio formats manually

Typical Symptoms

This fix may help if you experience:

• One speaker randomly losing sound
• Audio returning after changing inputs
• Intermittent speaker silence
• Dropouts during format changes
• Issues only occurring with certain streaming apps or movies

Setting the TV’s eARC mode to Auto resolves this issue in many installations.
