Appendix F: Surround Sound

Surround Sound over S/PDIF

The WDM drivers support transmitting surround sound-encoded data in either

Windows Media Audio or Dolby Digital formats via Layla3G and Gina3G’s

S/PDIF outputs. 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 Echo console.

 Select the digital output of your Echo product in the Windows “Sounds and

Audio Devices” control panel, under the “Audio” tab.

 In your Dolby Digital playback software, 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.
