How to fix no sound on RCA RPJ167?
- RRobin ChenAug 13, 2025
To restore sound on your RCA Projector, first, turn off Dolby Audio on the external device. If Mute mode is active, press the Mute button on the remote control. If external Bluetooth headphones/earbuds are connected, disconnect them. Also, adjust the sound settings on your video source device, as the issue might be due to non-Dolby support.
