Enhanced Audio Playback: To achieve 5.1 channel output via the optical fiber, certain conditions need to be met: the audio source must be DTS 5.1 channel, such as 3D games or HD movies. The player software settings are crucial, where using Power DVD software, selecting "Passthrough" for optical output ensures that the external audio card only outputs the optical signal without decoding. The KMP player is recommended for its powerful features. 5.
