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.
