If Audikast is receiving a valid audio signal and the headphones are connected, check the volume.
Check the Volume
- Make sure the headphones are not muted.
- Increase the headphone volume.
- If you are using AUX, increase the volume on the TV or connected audio source.
- Play the TV program again and test the sound.
Still No Sound?
If Steps 1–3 are correct but you still cannot hear sound, open the option that matches your situation.
Try Reconnecting the Audio Cable
Disconnect the audio cable from both the TV and Audikast.
Reconnect it securely at both ends, then play TV audio again.
If possible, try another compatible audio cable.
Sound Worked Before but Suddenly Stopped
A TV software update or settings change may have changed the digital audio format.
If you are using Optical, check the TV audio settings again and make sure PCM is selected.
Check TV PCM Settings →No Sound Only on Netflix, Prime Video, or Another Streaming App
If normal TV audio works but a streaming app has no sound, the app or streaming device may be using a different audio format.
Set the streaming device audio format to PCM or Stereo when available.
