Routing example

Audio Interface FocusRite Saffire Pro 40
Input Source External SPDIF stereo source
Output 4 analog channels
Method Internal routing


We want to use Ekio to filter the audio stream emitted by an external SPDIF stereo source. Ekio transforms the input stream into an output stream composed of 4 analog channels, which are sent to four amplifiers.


The solution proposed is the following:

It is performed with the following links:

Link 1:

The external source is connected to the SPDIF input of the sound card.

Link 2:

The Saffire Pro40 card automatically performs this connection. All physical inputs are directed to the ASIO inputs including the SPDIF inputs that interest us. So there is no special configuration of the sound card required here.

Link 3:

Within Ekio, we start by choosing the Saffire sound card.

Then, we select the entries of interest. Notice how all the physical inputs of the card are listed, including the SPDIF ones. We choose the SPDIF inputs, so channels 9 and 10.

Link 4:

For outputs, 20 DAW channels are offered. But the WDM drivers occupy the first channels. If Windows is configured for 2.0 output, channels DAW1 and DAW2 are busy. If Windows is configured for 5.1 output, channels DAW1 to DAW6 are busy. If Windows is configured for 7.1 output, channels DAW1 to DAW8 are busy.

We avoid the first channels and we configure Ekio so that it comes out of channels DAW9, DAW10, DAW11 and DAW12.


Do not take in consideration the names used for the output channels. They copy the names of the physical outputs and do not correspond to the current routing.

Link 5:

In MixControl, we connect the physical outputs:

DAW9 ➜ Monitor Output 1

DAW10 ➜ Monitor Output 2

DAW11 ➜ Line Output 3

DAW12 ➜ Line Output 4

Link 6:

Analog outputs 1 to 4 are connected to four amplification channels.
