No Audio Output Device is Installed

Hi,

You will need to select Windows 8 from the drop down list while installing the driver in compatibility mode.

I would suggest you to try setting the speaker as default audio output by following the steps below and check if it helps.

1. Right click on the sound icon on the right bottom corner of the taskbar.

5. Save the changes.

Let us know the result.
