Instructions
Connect your Sony PlayStation 3 to your television set or home theater receiver using either an HDMI cable or the Sony audio/video cables. Your PlayStation 3 will have come with the Sony audio/video cables, but an HDMI cable will need to be purchased separately.
Turn on your Sony PlayStation 3.
Select "Settings."
Select "Sound Settings" and then "Audio Output Settings."
Use the menu on screen to select the type of audio cable you used to connect your PS3 to your television or home theater. This will make sure that the PlayStation 3 is outputting audio from your games and movies in the correct format. Once you've done this, select "Save." Your PlayStation 3 will now be hooked up to your television or home theater without using an optical cable for surround sound.
