Hi, did you follow the instructions I gave you in your a previous thread?
As you didn’t react you may have overlooked it.
Next question:
Whenever you select a sound device in the list from “Audio Settings” you can change the settings for THIS one selected device in the window.
mAirlist saves the settings when you click “Save” although it displays another device when you re-open the window.
BUT this has nothing to do with the audio routing.
Or are you not capable at all to change the device in the selection field and it jumps back to the Realtek sound card right away?
Please try to select your Realtek Soundcard and test if the error still appears. If not, then the driver for the DDJ-SX may be the problem.
I own it myself but I’m using it only as a DJ console without connection to mAirlist. Is it possible to use all of the 4 channels independently in the audio routing settings?
IMPORTANT: Always use WASAPI in the Audio Routing f possible. DirectSound is old and can lead to buggy sound output.
Please report back.
