wasapi: Deal with HDMI or DisplayPort-based audio devices. They can vanish for UP TO EIGHT SECONDS...! This is for devices that connect to HDMI/DisplayPort/etc, where it presumably has to wait for a display to get up and running before it can play audio through it, so one can see the audio device fail when changing display modes, or the system returning from sleep. Since this can be triggered by a game changing video resolutions at startup (either before or after opening the audio device!), it's important to deal with. In normal conditions, it shouldn't take this long to open or recover an audio device, but this is better than unexpectedly losing the device in this situation. Fixes #7044. Fixes #5571.
