It is well-known that DTS5.1 can guarantee super high quality of the output. As far as I am concerned, Mac Blu-ray Player does support DTS5.1 initially in the world. Now, it can support DTS5.1 in v.1.9.5 and its upper versions for both Mac and PC system. And the process is easy to follow:
First of all, download Mac Blu-ray Player in v1.9.5 and upper versions from our official website:
Then get an optical fiber cable. Connect one connection to the audio output terminal of Mac, and the other end to the loudspeaker box through the digital optical port. Now it is the normal playback format. The effect presents stereo on the screen of the loudspeaker box.
Click “Tool” in the tool bar of the Mac Blu-ray Player. Then open the “preference” in “Tool”. Choose “Audio” and select the option of “Use S/PDIF when available”. Finally, click “OK” to start. Now the effect presents “dts Digital” on the screen of the loudspeaker box. And you can enjoy the HD Blu-ray movies with high quality.
