[SOLVED] Why can't I set one of my audio devices as default on Windows 10?

[PhilipIsBored]

I go into the Sound Control Panel but the "Set Default" button is greyed out and I cant click it but the audio device works just fine.

If you only have one sound device (ie a set of speakers) there is no need to set a default, that's the most common reason why it would be greyed out.
