Using EKIO with a WDM sound card (non-ASIO)

This tutorial describes a way in which to make EKIO filter the sounds emitted by Windows applications, and play the result through a WDM sound card.

This procedure needs to be performed only once because the settings will be kept for future use.

  1. Start by installing the following software:
  2. Run EKIO and create a new config by clicking the File/New menu.
  3. In the "Settings" tab, select the ASIO4ALL driver.
  4. Open the ASIO4ALL configuration window by clicking its icon in the system tray ( ).
  5. Click the spanner located in the lower right of the window to activate the "Advanced Options."
  6. Select the VB-Audio Hi-Fi Cable inputs. Select your sound card’s outputs. Uncheck all of the other lines. VB-Audio Hi-Fi Cable outputs must NOT be selected.

  7. For the changes to take effect, you must disconnect EKIO from the ASIO4ALL driver. To do so, go to the Settings tab and select the driver NONE. Then you can select ASIO4ALL again. The changes are now applied.
  8. Within EKIO, go to the Inputs/Outputs tab. Create, for example, two inputs and two outputs and connect them together in the Routing tab.

    In the Inputs/Outputs tab, select the input channels "VB-Hi-Fi Audio Cable 1" and "VB-Audio Hi-Fi Cable 2". Select output channels 1 and 2.

  9. Now, you can start audio processing by clicking on the playback button. Save the config on a disk if you want to load it again later.

  10. If you want all Windows applications to play through EKIO, right-click the volume icon in the system tray, click Playback Devices, right-click the "CABLE Input" listed and then choose Set as Default Audio Device.

    If you want a specific application to play through EKIO, go to the application’s preferences and choose "CABLE Input" as the output device.


In our example, the input channels are forwarded directly to the output channels without modification. This is not very useful.

Configure EKIO so that it executes the processing you want. Create the inputs and outputs that you need. Connect them. Set the filters, gains and delays that you want to apply.
