Transferring audio from a personal computer to a television can be accomplished by connecting the two components with a High Definition Media Interface (HDMI) cable. The six-sided plug on the cable delivers high-definition picture and up to eight channels of digital sound through a single connection to a TV equipped with an HDMI jack. Newer computers feature one or more HDMI OUT ports for connecting a PC or laptop to external audio/video equipment, plus the necessary drivers for processing the signals. The HDMI cable can be connected directly to a television or to a home theatre receiver hooked up to a TV. With the latter set-up, the user can enjoy surround sound audio if the receiver is connected to a multichannel speaker package.

Shut down the computer while connecting AV cables.
Locate a free HDMI OUT port on the back of the PC's Central Processing Unit (CPU) or the back edge of a laptop. The six-sided port contains 19 holes arranged in two rows. Insert the plug on one end of an HDMI cable, with the wider end of the plug facing upward, straight into the port until it clicks in place. Do not attempt to force the plug; it only inserts in one direction.
Connect the plug on the other end of the cable to an HDMI IN port on the back of the TV.
Turn on the computer and television, then start an audio program or file, such as playback of a digital music file stored on the computer. In a Windows platform, Media Player is the default program for audio playback. Apple systems typically use either iMac or QuickTime for playing audio files. Alternatively, open a web browser and go to a web page with sound, such as an Internet radio site.
Adjust the volume output on the computer by double-clicking the small speaker icon typically located in the lower right-hand corner of the screen, then use the mouse to slide the volume control to the desired level.
Press the "Volume" control on the TV or use the TV's remote control to adjust the volume in the set's built-in speakers.
Tips and warnings
- Connect the HDMI cable from the PC to an HDMI IN port on an AV receiver that is hooked up with surround sound speakers and attached to a television, if desired, to hear multichannel audio from the PC through the speaker package connected to the AV receiver.
- HDMI cables are among the most expensive audio/video cables in use with modern equipment. Use caution and a gentle touch when inserting the plug to an HDMI port and be sure the plug is oriented in the correct direction to avoid bending or breaking any of the 19 steel pins inside. Breaking a pin will ruin the cable and necessitate a replacement.
