Troubleshooting Steps for Fixing Soundbar Issues
If you’ve connected your Dolby Atmos soundbar but aren’t getting any audio, try these troubleshooting tips:
Check Wire Connections
Make sure HDMI and power cables are securely inserted into the soundbar ports without any looseness or damage. Snug connections are key.
Inspecting cable connections:
- Examine cable ends for any bent or missing pins
- Ensure cables are plugged into correct ports
- Remove and firmly reinsert all connectors
Select Proper Audio Input
Soundbars have multiple audio inputs. Make sure the correct one that the source is connected to, like HDMI ARC or Optical, is selected as the active input.
Choosing the proper input source:
- Reference soundbar manual to identify inputs
- Press the Input button on the remote
- Cycle through and select the correct input
Enable HDMI-ARC on TV
The TV must have HDMI-ARC enabled in its settings for audio signal transmission to the soundbar. DIGITAL AUDIO OUT must also be on.
Enabling HDMI-ARC on the TV:
- Access your TV’s audio settings
- Locate options for HDMI-ARC and DIGITAL AUDIO OUT
- Ensure they are enabled
Set Audio Output to Soundbar
The TV’s audio output must be set to external speakers to transmit sound to the soundbar instead of internal TV speakers.
Changing audio output:
- Go into your TV’s audio settings
- Look for options to select speakers
- Choose external speakers option
Update Firmware
Outdated soundbar firmware can cause compatibility issues. Connect the soundbar to WiFi if possible to enable firmware updates. Always keep the system up-to-date.
Updating soundbar firmware:

- Connect soundbar to WiFi if possible
- Check for any available firmware updates
- Install updates when prompted
Adjust Soundbar Modes
Toggle through the different sound modes or listening profiles on the soundbar using the remote. This cycles through available codecs.
Changing the sound mode:

Power Cycle Devices
If connections seem right but no audio, try power cycling the TV, source device, and soundbar by turning them off and back on fully. This reinitializes signal recognition.
Power cycling the equipment:
- Fully power off the soundbar, TV, and source
- Unplug devices for 30 seconds
- Plug back in and power on equipment

As a last resort, reset the soundbar to factory defaults to clear any faulty settings causing issues. You’ll have to reconfigure initially.
Resetting to factory settings:
- Locate factory reset instructions in manual
