How to configure HP Desk Top for 4 speakers

[Ronbo63]

The box said the PC had 5.1 surround sound, but only lets me plug in my green speaker wire. There is no black port on back. Is there a way to configure the blue or red for the rear speakers?

@Ronbo63 That would mean that the device supports 5.1 surround sound system, however, if the sound card doesn't have an SPDIF port, or the speaker you have doesn't have a cable that supports the desktop's audio card, it wouldn't work, in this scenario, you may need to either upgrade your audio card to the one that supports 5.1 channel output or get a speaker that does the same via the green speaker port (audio).

For details on how the SPDIF port works, check the below information:

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.
