Aura Loop – Troubleshooting: No Sound

If you have successfully connected Aura Loop but hear no sound, please follow the steps below in order:

1. Check All Cable Connections

• Make sure the USB-C power cable is properly connected to the TV’s USB port or a power outlet.

• Ensure the audio cable is firmly plugged in:

  • Optical: Transmitter OPTICAL → TV Optical Out

  • AUX: Transmitter AUX → TV Headphone / AUX Out

• Try unplugging and reconnecting the cables to ensure a secure connection.

• If you are using a soundbar with HDMI-ARC, temporarily unplug it and test Aura Loop again.

2. Confirm TV Audio Settings (Very Important)

If using Optical, please check your TV settings:

• Sound Output → set to Optical

• Digital Audio Format → set to PCM

⚠️ Other formats such as Dolby, Auto, or Bitstream will NOT work with Aura Loop.

If using AUX (Headphone jack):

• Set TV Sound Output to Headphones

3. Check Transmitter Status

• The Audio Input LED on the transmitter should be solid white, indicating a valid audio signal.

• If there is no light, the TV is not sending audio to the transmitter — recheck Step 2.

4. Check Earbuds & Connection Status

• Make sure the earbuds are powered on.

• When connected via Auracast, the earbud LED should be solid orange.

• If not connected:

  • Turn the earbuds off, then on again to rejoin the Auracast broadcast.

5. Check Volume Levels

• Increase the volume using:

  • The earbud volume buttons

  • Your TV remote

• If using Optical and the sound is too low, press the Volume Boost button on the transmitter (LED will turn solid white when activated).

6. Test with a Different Audio Source

• Play a different TV program, app, or video to rule out source-related issues.

• If possible, test Aura Loop with another TV to confirm normal operation.
