Aura A40 Noise Problem?🔥🔥

Please try the troubleshooting as follows:

1. We recommend using an OPT (optical) connection between the soundbar and your TV for optimal performance. After connecting to the TV, try setting the TV's audio output to PCM:
   TV Settings > Home > Settings > Sound > Digital Audio Output > PCM.
2. Connect the phone and soundbar via Bluetooth.
3. Replug the optical cable and ensure all connections are tight. If the issue persists, it may be caused by faulty cables; please try replacing the optical cable to see if it resolves the issue.
4. You can also try a factory reset:
   With the soundbar powered on, press and hold the "DEVICE RESET" (or Mute) button on the remote for 5 seconds to initialize the device. The soundbar's LED will display "RSET" when complete.
5. Change other audio sources for testing.
    

If the issue continues via optical and Bluetooth connection, please contact our support team[support@ultimea.com] for further assistance with after-sales solutions.
