Instructions
Plug an audio output cable from your PS3 to your stereo system. The simplest way to do this is to use either a fiber-optic digital audio cable or component cables. The digital audio cable is a dedicated cable for audio signals only. The component cable has two jacks that carry audio signal -- one red, the other white or black. Plug one of these options into the appropriate ports on your stereo.
Set your stereo to the audio input you plugged the PS3 into. This will differ depending on the type of cable you used and the type of stereo you have. The stereo owner&'s manual should describe how to switch between audio inputs.
Configure your PS3 to output audio over the type of cable you used to connect it to the stereo. Go to the "Settings" column of the PS3&'s main menu, select "Settings," then "Audio Output Settings." This will bring up a list of three audio output options: "HDMI," "Digital Out (Optical)," and "Audio Input Connector/SCART/AV MULTI." If you used the fiber-optic cable, select "Digital Out (Optical)." If you used component cables, select "Audio Input Connector/SCART/AV MULTI."
Select an audio output format from the following menu that is compatible with your stereo system -- 2 channel, Dolby 5.1, Dolby 7.1, etc. If you are using stereo headphones, your stereo will automatically convert any audio signal from the PS3 to 2 channel.
Plug your headphones into your stereo. Most stereos will automatically output audio only to headphones when they are plugged in. The stereo owner&'s manual should describe how to switch to headphone output if it doesn&'t switch automatically.
