AuraPlex MX - Troubleshooting: No Sound

If you experience no sound when using AuraPlex MX, please follow the steps below.

1. Check the Audio Source

• Make sure the audio source (TV, sound system, microphone, or phone) is actively playing audio.

• Increase the volume on the audio source to confirm sound output.

2. Check the Transmitter Input Mode

• Confirm the transmitter is set to the correct input:

  • Bluetooth

  • Optical (OPT)

  • AUX

• If the input LED is blinking, the transmitter is not receiving a valid audio signal.

3. For Optical (TV) Input

• Go to your TV’s audio settings.

• Set the audio output format to PCM.

• Dolby / DTS formats are not supported and may result in no sound.

4. If Using Avantree Receivers

• Make sure the receiver is powered on.

• Plug wired earphones fully into the receiver.

• Adjust the receiver volume.

• If the receiver LED is blinking orange, turn the receiver off and then on again to rejoin the broadcast.

5. If Using Your Own Hearing Aids

• Confirm your hearing aids are Auracast-compatible.

• Make sure the hearing aids are powered on and connected to your phone.

• Open your hearing aids’ companion app or Auracast assistant.

• Re-scan for available Auracast broadcasts.

• Select the Oasis Aura broadcast to join.

• Move closer to the transmitter and try again if the broadcast does not appear.

Note: Not all hearing aids support Auracast. Please check with your hearing aid manufacturer for compatibility.

6. Still No Sound?

• Restart the transmitter and receivers.

• Try a different audio input (AUX or Bluetooth) to rule out source issues.

• Contact Avantree Support for further assistance.
