This document pertains to HP and Compaq desktop computers with Windows 7.

This document shows how to connect headphones or speakers to your computer. Use this document to configure the audio settings, determine the correct connection port, and begin using your external audio device on your computer.

NOTE: 

This is not a troubleshooting document. If there is no sound coming from your speakers or headphones, see HP Desktop PCs - No Sound from the Speakers or Headphones (Windows 7).

Connecting headphones

This section describes the ports and connector plugs needed to use your headphones with your computer.

NOTE: 

To set up headphones with wireless Bluetooth technology, see HP PCs - Connecting a Bluetooth Device (Windows).

Connector

Your headphones have a three-segmented or four-segmented connector plug. Both produce sound when plugged into a headphone connector. The three-segmented plug is for headphones only. The four-segmented plug supports a headphone and an attached microphone.

Port

Insert the headphone plug into the port on the computer marked with a diagram of headphones.

After connecting headphones, configure the sound settings using the steps in Setting the default sound device.

Connecting speakers

The following sections describe the ports, plugs, and cables needed to use speakers, and a variety of speaker configurations to use with your desktop computer.

Configuring 5.1 and 7.1 surround sound speaker systems

Use the following steps to connect 5.1 and 7.1 surround speaker systems to the computer:

NOTE: 

If your speaker system supports SPDIF through a coaxial connection, connect an RCA-style coaxial cable to the orange SPDIF port on the back of the computer and to the main speaker, and refer to SPDIF digital settings.

1. Unpack the speakers and assemble each component following the manufacturer's instructions.
2. Position the speakers, trying to place each of the speakers an equal distance from the center of the listening area.

   • Place the subwoofer on the floor near the computer. Make sure that the connectors on the back of the subwoofer are easily accessible and the speaker faces forward.
   • Place the center speaker on top or in front of the monitor.
   • Place the front left and front right desktop speakers on either side of the monitor.
   • Place the rear left and rear right speakers behind the listening area.
   • For 7.1 surround, place the left side and right side speakers as close to the sides as possible, usually toward the front of the desk.
3. Following the directions that came with the speakers, connect the speaker wires between each speaker and the subwoofer, making sure to connect each speaker wire into the matching port.

   NOTE: 

   Use the longer speaker wires for the rear speakers.

4. Place the control tower (the volume control component) near the listening area where it is easily accessible, and plug the cable from the control tower into its matching port on the back of the subwoofer.

   NOTE: 

   If your speaker system supports SPDIF through a coaxial connection, connect an RCA-style coaxial cable to the orange SPDIF port on the back of the computer, and to the main speaker. Refer to SPDIF digital settings.

5. Connect the sound cable with green connectors into the Primary Front Speaker Out port on the back of the computer. Plug the other end of the cable into the green port on the subwoofer.
   
6. Connect the sound cable with black connectors into the Rear Speaker Out port on the back of the computer. Plug the other end of the cable into the black port on the subwoofer, next to the green port.
   
7. Connect the sound cable with orange connectors into the orange Center or Digital Out port on the back of the computer. Plug the other end of the cable into the orange port on the subwoofer.
   
8. Plug the speaker cord into the electrical outlet and turn on the speaker system.
9. Turn on the computer and test for sound.
   Configure the sound settings using the steps in Setting the default sound device.

Configuring speakers connected to a home stereo receiver (digital SPDIF or analog with RCA-style cables)

Depending on your computer and stereo receiver, you can use either an analog (RCA style) or digital (SPDIF or HDMI) connection:

• An analog connection uses an adapter cable to connect the audio-out ports on the computer to the RCA-style connections on the receiver.
• A digital connection uses a SPDIF or HDMI cable to connect the computer and receiver.

NOTE: 

Not all computers come with digital audio capability. You need a Digital Out port or HDMI connection.

To set up an RCA-style analog connection, use the following steps:

1. Purchase the necessary number of Y adapter audio cables as described in the following list.

   NOTE: 

   Make sure that the cables are long enough to reach from the back of the computer to the back of the receiver or amplifier. These adapter cables have one 3.5mm (1/8 inch) stereo miniplug on one end and two RCA-style connections on the other end.

   
   • If the home stereo system has two speakers, buy one Y adapter cable.
   • If the home stereo system has four speakers, buy two Y adapter cables.
   • If the home stereo system has a 5.1 or greater speaker system, buy three Y adapter cables, plus one more cable for each extra set of speakers beyond the initial 6. For example, buy three cables for a 5.1 system, and four cables for a 7.1 system.
2. Turn off the stereo receiver or amplifier, and connect the cables between the receiver and the computer using the following instructions:
   • Front speakers: Connect the stereo miniplug on the Y adapter cable into the Speaker Out (green) port on the back of the computer.
     
     Connect the other ends of the Y adapter cable into the Left In and Right In ports on the back of the stereo receiver or amplifier (usually CD or DVD in).
     

     NOTE: 

     If your stereo is a 5.1 or higher system, use the front left and right inputs labeled DVD, Surround, 5.1, or 6 Channel.

   • Rear speakers: Connect the stereo miniplug of a Y adapter cable into the Rear Speaker Out (black) on the back of the computer. Connect the other ends of the Y adapter cable into the Rear Left and Right inputs on the back of the stereo receiver or amplifier labeled DVD, Surround, 5.1, or 6 Channel.
     
   • Center and subwoofer speakers for 5.1 or higher system: Connect the stereo miniplug of a Y adapter cable into the Center or Digital Out (orange) on the back of the computer. Connect the other ends of the Y adapter cable into the Center and Subwoofer inputs on the back of the stereo receiver or amplifier in the section labeled DVD, Surround, 5.1, or 6 Channel.
     

     NOTE: 

     Plug the Y adapter cable into the Subwoofer port on the back of the receiver or amplifier even if the stereo system does not have a subwoofer.

3. Turn on the stereo and select the music source on the front panel. This is the component that the Y adapter cable is plugged into (usually CD, DVD, or 5.1) as the source.

   NOTE: 

   Check the stereo user guide for instructions on setting the music source.

4. Configure the sound settings using the steps in Setting the default sound device.

To set up an SPDIF digital connection, use the following steps:

NOTE: 

You can use a standard RCA-style audio cable for a SPDIF connection.

1. Turn off the stereo receiver or amplifier.
2. Connect the cable into the Digital Out port on the back of the computer.
   
3. Plug the other end of the cable into the receiver. This is usually labeled SPDIF, COAXIAL, or Digital In port on the receiver.
4. Turn on the stereo and select the music source on the front panel.

   NOTE: 

   Check the stereo user guide for instructions on setting the music source.

5. Configure the sound settings using the steps in Setting the default sound device.

To set up an HDMI digital connection, use the following steps:

1. Turn off the stereo receiver or amplifier.
2. Connect one end of the HDMI cable to the HDMI output on the back of the computer.

   NOTE: 

   The HDMI port is located on the graphics card or the motherboard.

   
3. Connect the other end of the HDMI cable to the HDMI input on the stereo receiver.
   
4. Turn on the stereo and select the music source on the front panel.

   NOTE: 

   The video or TV signal/input source needs to match the connector. Check the stereo user guide for instructions on setting the music source.

5. Configure the sound settings using the steps in Setting the default sound device.
