ŒŒ If you are using an external device, check the device’s audio output option (ex. you may need to change your cable box’s audio option

to HDMI when you have a HDMI connected to your TV).

ŒŒ If you are using a DVI to HDMI cable, a separate audio cable is required.

ŒŒ If your TV has a headphone jack, make sure there is nothing plugged into it.
