Before You Start: No sound may occur if the earbuds are disconnected, the TV audio settings are incorrect, or the transmitter is not receiving audio.
Step 1 – Check the Earbud Connection
Remove both earbuds from the charging base and keep them near the transmitter. Check the earbud LED.
Earbuds Not Connecting?
- Put both earbuds back on the charging base.
- Wait a few seconds.
- Remove both earbuds again.
- Keep them near the transmitter until the LED turns solid orange.
Step 2 – Check the Audio Signal & Settings
Play TV audio and check the transmitter's Audio Input light.
Why PCM? Medley Pebble 2 needs a compatible stereo audio signal. If your TV sends Dolby, Auto, or Bitstream audio, you may hear no sound. For Optical connections, select PCM / Stereo.
Choose your TV connection type and follow the matching instructions.
Step 3 – Check Cable Connections, Volume & Restart
1. Check the cable connection:
Make sure the cable is securely connected to the TV and the correct input port on the transmitter.
Connect to the transmitter's OPT input from TV.
Connect to the transmitter's AUX input from TV.
2. Check the volume and test again:
- Press the + button on the earbuds several times to increase the volume.
- If using AUX, also increase the TV volume.
- Try another TV channel or video.
- Try a NEW audio cable of the same type.
- Still no sound? Restart the transmitter and earbuds, then test again.
