Some TVs are not recognized by the computer as an HDMI® device, but instead, are recognized as a DVI device. Since DVI connections do not support audio, the computer is unable to transfer audio to the TV with an HDMI connection. The computer will still support audio output through other audio connections.
To output audio to the TV, connect the composite audio output on the computer to the composite audio input on the TV. On a notebook computer, connect the headphones jack to the composite audio input on the TV. Be sure to use the audio input on the TV that is adjacent to the HDMI connection.
NOTE: For more information about audio outputs that are available on the computer, consult the Users guide.
