Windows 7, Nvidia GeForce GTX 950
Broken: 2.79 5bd8ac9
I load up the VSE and then plug in or remove my USB headphones. After this, when I hit play (which I have bound to space), the Video Sequence Editor pane no longer runs at the correct FPS (it is much faster) and there is no audio out of either output. Returning the audio output device to the original state does not fix the problem.
Exact steps for others to reproduce the error
I don't know the make of my headset, but they are gaming headphones with an attached mic. The audio driver is called USB PnP Sound Device.
