Things You'll Need
Instructions
Turn on the television and PS3.
Select the "Settings" icon (it looks like a briefcase) using the controller direction buttons.
Navigate to "Sound Settings" by pressing the direction buttons to the right.
Select "Audio Output Settings" from the sound settings list.
Select the interface that you use to connect to your audio system. Suppose it is "Digital Out (Optical)," which is the preferred interface for the BitStream audio setting.
Navigate down the list of audio formats until you find "BitStream." Select this and press the "X" button to place a check inside the box to the left of "BitStream." It is now selected for use.
Press the right button on your controller and then press the "X" button. The settings are saved and your audio will now support BitStream audio.
