If one is selected in the Preferences we pass that in as the preferred device name when we open the audio output.

We use the JUCE library's AudioDeviceManager to build the list we display of the the available audio outputs on the system. The origin of the problem here is that the meaning of the Default playback audio device should rather be the currently used default audio device (at least on startup of OpenShot due to the restart issue), which is not the case at the moment. I had to go into Preferences -> Preview -> Playback Audio Device and select that device and had to restart OpenShot (which is something that shouldn't really be needed but I can live with that). Therefore I am plugging in a Realtek USB headset and once it is plugged in, the OS (Windows 10 1909) uses this as the default sound output and any app respects that except for OpenShot.

Default audio output when nothing is plugged in, are the laptop speakers (which do not work for me).
