Click on Options in the function bar below the main menu and select Global Options - Sound cards WDM on the left.
For driver type select WDM. If you choose ASIO the dialog for ASIO sound cards will appear.
Note: Output via ASIO drivers allows multi-channel sound even with standard sound cards or onboard sound chips, provided they have several outputs. You only need to install software tool ASIO4ALL which is available on the web at www.asio4all.de.
Here you select the range of channels to be displayed in the list below, i.e. outputs 1 - 8 to outputs 25 - 32.
From the list select the required output of your sound card for audio playback. Output of two channels (stereo sound) is preset for the first audio output. If you choose Windows Default device the sound card chosen in the Windows Control Panel under Sound is the active one.
If option SPDIF/AC3 is enabled, AC3 data stream can also be output via the S/PDIF output. Important: Output depends on certain conditions and restrictions. See Playback of coded AC3 data streams.
If the Pro License or higher has been installed, you can assign up to 12 stereo outputs of your sound cards to the stereo outputs in Wings Vioso RX. You can use several standard sound cards or multi-channel sound cards.
By clicking one of the fields next to the outputs, you can select the background color for the level display. Details on color selection. In order to display the individual background colors, deactivate the standard colors under Global Options - Audio Level.
The figure (in brackets) in the track head of the audio track indicates which output the track is allocated to.
The channels of multi-channel sound cards for WDM drivers must be selectable in the form of several stereo outputs, which is not the case for so-called 5.1 sound cards. You can bypass this restriction by using the tool ASIO4ALL and the ASIO driver for your WDM sound card. See Sound cards ASIO.
When using several standard sound cards, playing back may become asynchronous, as every sound card has its own time clock which makes differences unavoidable. The longer the running time, the more will deviations and tolerances become audible. Really synchronous playback can only be achieved with professional multi-channel sound cards.
If you want to playback multi-channel soundtrack as mixdown on a stereo output you can allocate this output several times. However, there are a few sound cards, that do not support this feature and will cause problems.
