Medley Pebble 2 – Troubleshooting: No Sound

If your Medley Pebble 2 is connected but you 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 Medley Pebble 2 again.

2. Confirm TV Audio Settings (Very Important)
If using Optical connection:

• Sound Output → set to Optical
• Digital Audio Format → set to PCM (Required)

⚠️ Formats like Dolby / Auto / Bitstream are not supported.

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

• Remove the earbuds from the base.
• When successfully connected via Auracast:
  → LED should be solid orange

If not connected:

• Put the earbuds back into the base, then take them out again
• Or restart the earbuds to rejoin the broadcast

5. Check Volume Levels

• Adjust volume using the earbud buttons (+ / −)
• Increase TV volume (if available):
  • Optical: TV volume may be fixed
  • AUX: TV volume may control sound
• If volume is still low:
  → Turn on Volume Boost on the transmitter

6. Test with Another Source

• Try a different TV channel, app, or video
• If possible, test with another TV to rule out TV issues
