Wdm Configuration - RME Audio Digiface Ravenna User Manual

7.2 WDM Configuration

The WDM Devices configuration has one
button to enter the edit dialog, a status dis-
play showing the number of currently ena-
bled WDM devices, and a listbox to select
between Stereo or Multi-Channel devices.
The number represents both record and
playback devices, so '1' means one input
and one output device.
The screenshot to the right shows the ste-
reo WDM devices available with the
Digiface Ravenna. Here the first four stereo
devices had been activated. Any can be ac-
tivated. Also only higher numbered devices
might be active. For example using 25+26
for system based audio does not require to
activate the prior stereo devices. Only Ra-
venna (25+26) will show up in the Windows
Sound control panel.
The checkbox All to the right allows for a
quick check/uncheck of all devices.

The screenshot to the left shows the multi-
channel WDM devices available with the
Digiface Ravenna after selecting 'Multi-
Channel' in the WDM Devices listbox and
hitting WDM Configure. In this example the
devices DRavenna 1-8, 9-16, 17-24 and 25-
32 are active.
Using a multi-channel WDM device allows
for the use of multi-channel playback with
specialized software as well as Surround
sound from DVD or Blu-Ray player soft-
ware.
Please note that configuring the WDM de-
vice to a specific surround mode in the con-
trol panel Sound requires the device to have
the Speaker property. See next page.
Again the checkbox All to the right allows for
a quick check/uncheck of all devices.
