The WDM drivers support transmitting Dolby Digital data via your hardware’s S/PDIF output.
The stream will bypass the kernel mixer and will be transmitted with bit-for-bit accuracy.
In order to use this feature follow, these steps:
-Select S/PDIF (RCA or Optical) digital mode in the console.
-Select the digital output of our card in the Windows “Sounds and Multimedia” control panel,
under the Audio tab. If you are using Mia or MiaMIDI, you can select any of the virtual outputs.
-In your Dolby Digital playback application, enable digital streaming.
For example, in WinDVD select “Properties…” and under the audio tab select Enable S/PDIF
output. If it is grayed out, double-check the control panel settings, then quit and restart WinDVD.
