If you are Mac/Linux users or really don’t want to install HDML-Cloner Pro Helper, It could be resolved by adjusting a few settings. Please proceed as follows:

Step 1: Adjust audio settings of your Windows computer.

  1. Connect ClonerAlliance Flint LXT to PC first. Right click on “Speaker” Icon of Windows desktop tray bar, choose “Recording devices”.
