Questions and answers
i have sound but no voice
The issue of sound but no voice on the JVC TH-G31 may be caused by the surround sound system not properly decoding or directing center channel audio, which typically carries dialogue. If the system is dropping the first second of audio or short sounds, as described, it could be due to a delay in signal processing or the receiver entering a low-power or standby mode between audio signals. This delay can cause brief or initial parts of audio, including voices, to be missed.
To resolve the issue, ensure:
- The correct input mode is selected on the receiver.
- All speaker connections, especially the center speaker, are secure and correctly wired.
- The audio output settings on the connected device (e.g., PS4) are set to match the surround sound format supported by the receiver.
If the center speaker is not working or the receiver fails to process its signal, voices may not be heard.
