No sound on OSNtv Android Box (including home theatre)

If you can see the picture but can’t hear sound, or the audio doesn’t sound right, follow these steps:

1. Make sure the TV and the OSNtv Android Box are not muted, and increase the volume on both.
2. Check the audio preferences. Depending on your setup, switch between Stereo and Dolby. You can also set the Audio Delay to 20 ms.
3. If an RCA audio cable is connected, disconnect it and use the HDMI cable for audio. Then select the matching HDMI input on the TV.
4. Check that the HDMI cable is firmly connected at both ends. Try another HDMI port or cable if available.
5. If your TV doesn’t support Dolby Digital or Dolby Digital Plus, go to Home > Android Settings > Device Preferences > Display & Sound > Advanced Sound Settings > Select Formats, then choose Never use surround.

If you use a home theatre system

1. Restart your home theatre system.
2. Check that the correct AUX or HDMI input is selected on the system.
3. Connect the OSNtv Android Box directly to your TV and check whether the problem is resolved.

Note: If the problem only happens when the home theatre is connected, check the home theatre settings or its manufacturer’s guide.
