I have to shut down and restart computer to reset audio device

The last few days while I worked on podcast projects in Audacity, it would tell me my audio output device was changed and wouldn’t play my project. I also messed with my audio playback for other apps like the Windows Music Player and my Chrome web browser. Is this an Audacity issue? If so, how do I correct it?

So if you are using a USB device in Audacity and you unplug it and then plug it back in (or perhaps just jiggle the cable), Windows changes the pointer to the device and it generally confuses Audacity. To resolve the issue, do Transport > Rescan Audio Devices.
