How to Change My TV to PCM

By Rob Kemmett

Pulse-code modulation, abbreviated “PCM,” is a form of digital signal that is used to represent analog data. PCM is the standard audio format for CDs, DVDs, computers and digital phone systems, and is an optional audio format on many televisions. Depending on the model of television you watch, switching the audio output to PCM may improve the sound quality of the television’s speakers.

Step 1

Press “Menu” on the remote control. If you do not have a remote control, press “Menu” on the television.

Step 2

Press the arrow keys on the remote to scroll to “Audio Settings.” If you do not have a remote control, press the “Volume Up” and “Volume Down” buttons to scroll.

Step 3

Press “OK” on the remote control. Press “Enter” on the television if you do not have a remote. If the television does not have an “Enter” button, the “Menu” button is often used.

Step 4

Scroll to “Advanced Audio” and press “OK.” Some televisions may not have an “Advanced Audio” menu and may list various audio settings instead.

Step 5

Scroll to “Audio Output Mode” or “Digital Audio Output Mode” and press “OK.”

Step 6

Scroll until “PCM” is displayed as the current audio output.

Step 7

Press “OK” to save the settings.
