Before You Start: No sound usually means the Aura Focus earbuds are not connected to the transmitter, the TV is not sending a compatible audio signal, or a cable or volume setting needs attention. Follow these three steps to find and fix the problem.
Step 1 – Check the Earbud Connection
Turn on the Aura Focus transmitter and take the earbuds out of the charging case. Check that the earbuds are connected to the transmitter.
Earbuds Not Connected? Disconnect them from other devices, then reconnect them to the transmitter.
How to Reconnect Aura Focus Earbuds →Step 2 – Check the TV Audio Signal & Settings
Play TV audio and check the transmitter’s audio input indicator.
Choose your TV connection type and check the matching settings.
Why PCM? For Optical connections, the transmitter needs a compatible stereo signal. Set the TV audio format to PCM / Stereo. Dolby, DTS, or Bitstream may cause no sound.
Step 3 – Check Connections, Volume & Restart
- Check that the audio cable is securely connected to the TV and transmitter.
- Increase the volume on the earbuds. You can also press + on the transmitter. For AUX, increase the TV volume too.
- Make sure the TV is not muted. Try another channel, video, or app.
- If there is still no sound, try a new cable of the same type.
- Turn off the transmitter and earbuds. Reconnect the audio cable, then turn them back on and test again.
No Sound on Certain Apps or Cable Boxes? Set the TV or streaming device’s digital audio format to PCM / Stereo.
