Step 1 - Enter Display Setting menu, tap on Audio.
Step 2 - From Audio menu, select Auto or turn off the built-in speakers (Varies for different models).
Step 3 - If you are using Optical/SPDIF Audio Out Port, tap on Digital Audio Out and select PCM. If you are using RCA Audio Out Ports, tap on Analog Audio Out.
