      If no sound is coming from your Epson Control Panel, or the sound is too faint, there are several things to check: * Verify that the projector's audio input setting is correct. * Make sure the audio volume of the projector or speakers isn't turned down too much. * Check the projector's 'MIC Input Level' to ensure it's appropriately adjusted. * Confirm that the audio cable of the connected device is correctly connected. * Ensure there is no cable connected to the projector's audio output port, as this can prevent sound from the built-in speaker. * Verify that the DIP switch setting is correct.
