Things You'll Need
Instructions
Determine the cable that will work with your surround sound system. The PS3 is capable of handling three different types of connections: Component video with a stereo cable; component video with a fiber optic audio cable; and HDMI cables, with each connection better than the one before it.
Connect the cable to the PS3, then connect the other end of the surround sound speaker system via the system's receiver device. The areas to connect the cable to will be labeled as such on each of the devices.
Turn on the surround sound system, then turn on the PS3. You should hear sound coming out of the speaker system.
