Using Dolby® Digital Live™ The Dolby® Digital Live™ technology encodes your computer's digital audio contents to real-time Dolby® Digital streams. Using the CODEC and the Sony/Philips Digital Interface (S/PDIF) ports on the motherboard, you can send the encoded Dolby® Digital streams to an AC-3 decoder for playback on a multi-channel speaker system. Refer to the following illustrations when converting sounds to Dolby® Digital streams. Direct or non-encoded audio in your computer passes through the AC-3 encoder. The AC-3 encoder converts the s o u n d i n t o D o l b y® Digital streams. The audio CODEC processes the streams then passes it to an AC-3 decoder through the S/PDIF out port. 1 CMI9880 CODEC 2 3 To enable the Dolby® Digital Live™: 1.
