The message [Error: Failed to connect audio!!] is shown, or the virtual deck disappears immediately on the Serato DJ Lite screen. Why?

The installation of the driver software might be incomplete or the connection might be causing a problem.

If you've already installed the driver software, try again in the following sequence:

■ Windows

1. Close Serato DJ Lite and disconnect the OMNIS-DUO from your computer.

2. Open the control panel (or [Start] > [Settings] > [Apps]) and uninstall [OMNIS-DUO Driver].

3. Quit Windows.

4. Disconnect other USB devices, USB hubs, etc.

5. Start Windows.

6. Download the driver software from [here].

7. Install the driver software again.

　*An error will occur when the license agreement screen is displayed and you try to proceed without marking the [Agree] check box and clicking [OK].

8. Connect the OMNIS-DUO to another port without using a USB hub, etc.

If you still experience the problem, it might be caused by operating system sound settings, etc.

Follow the instructions in the troubleshooting guide Case 3 or Case 6 [here]

*The guide is for rekordbox users but you can fix the problem in the same way.

■ Mac

It might be caused by operating system sound settings, etc.

Remove all other USB devices from your Mac, uninstall the virtual audio device etc, and restart the Mac.
