If a source device is used

 

•• Make sure the audio cable is properly connected to the audio input port on the product.

 

•• Check the audio output settings for the source device.

 

(For example, if an HDMI cable is connected to the monitor, the audio setting for the

 

cable box may need to be changed to HDMI.)

 

 

 

If a DVI-HDMI cable is used, a separate audio cable is required.

 

 

 

If the product has a headphone port, make sure nothing is connected to it.

 

 

 

Reconnect the power cable to the device and then reboot the device.

 

 

There is static coming from the speakers.

Check the cable connection. Make sure a video cable is not connected to an audio input port.

 

 

 

Check the signal strength after connecting a cable.

 

 

 

Low signal level can cause corrupted sound.

When Speaker Selection is set to External Speaker, the volume button and mute function are

 

disabled.

 

Adjust the volume for the external speakers.

 

 

 

Audio settings for main speakers are separate from the internal speakers on the product.

 

Changing or muting the volume on the product does not affect an external amplifier(decoder).

 

 

There is an echo sound coming from the speakers.

Different decoding speeds between the product speakers and external speakers can cause an

 

echo.

 

In this case, set Speaker Selection to External Speaker.
