Dolby Audio Processing (DAP) is a suite of post-processing technologies designed to improve the audio playback experience on a TV using TV speakers.
The TV is set to Auto by default for digital out, which means that the TV can automatically recognize and output the corresponding audio format.
When TVs are connected to 5.1-channel or 7.1-channel audio speakers, the TV has automatically recognized speakers and outputs the corresponding audio format to them, and then we can directly personalize the Dolby sound effect through Dolby audio processing to improve the experience.
NOTE: If there is no sound after connecting 5.1-channel or 7.1-channel audio speakers, please refer to the following path to manually switch the digital out setting according to the type of speakers you connect.
Settings > Device Preferences > Sound > Digital Output > Dolby Digital /Dolby Digital Plus
