NOTE: Dante Virtual Soundcard stereo pairs will appear as selectable audio interfaces in
Windows regardless of the current mode - i.e. with Dante Virtual Soundcard in ASIO mode, it
will still appear as a set of selectable audio interfaces in the Windows sound playback options
dialog. Similarly, in WDM mode, it will appear as a selectable audio interface in an ASIO-
supporting DAW. However, it will not function correctly unless the currently selected mode
matches the requirements of the application.
5.5.4. Windows Audio Shared Mode.
Windows allows applications to share audio interfaces.
If applications with differing sample rates share an audio interface, their sample rates are
automatically brought into line by Windows, so it can mix the audio streams. This will result in
sample rate conversion on one of the audio streams, which can adversely affect audio quality.
To prevent Windows performing sample rate conversion on "Dante Virtual Soundcard" audio,
the "Shared Mode" default format for all "Dante Virtual Soundcard" channels should be set to
match the sample rate currently selected on the "Dante Virtual Soundcard" control panel.
In Windows 7, the default shared mode format for the device is automatically updated when the
audio format of "Dante Virtual Soundcard" is adjusted in "Dante Controller", so you should not
have to adjust it manually.
In Windows 8.x, you will need to manually specify the default shared mode format for the
device:
1. Open the Windows Sound options dialog (Start > Control Panel > Sound).
2. With the "Playback" tab selected, double-click the "DVS Transmit 1-2" entry in the
interface list.
The "DVS Transmit 1-2 Properties" dialog is displayed.
3. Select the "Advanced" tab.
4. Set the Default Format to the required setting.
5. Click OK.
6. Repeat for all "Dante Virtual Soundcard" stereo pairs.
7. Repeat again for the "Recording" tab.
8. Click OK.
