 I'm not sure if we have the same issue or not. Windows should default to stereo even if you select 5.1 or 7.1 in the Windows sound configuration wizard. It was stuck in multichannel after playing a multichannel source. Any upconversion of the stereo source should be done by the AVR unless specified by the media player or decoder. So, I can play a stereo source from a video add-on and it won't playback in 5.1; it is stereo and upconverted to Pro Logic II by the AVR. 

I select the AVR as the audio device, which is the device connected to the HDMI port of the GPU. Selecting Nvidia (High Definition Audio) is also a device connected to the same HDMI port, but it specifies the graphics card as the device rather than the AVR. These two devices corrected my issue by overwriting the error caused with the AVR device. The Nvidia (High Definition Audio) device seemed to overwrite the settings for AVR connected to the same HDMI port.

If uninstalling and reinstalling a different driver corrects your problem, then we don't have the same issue, as this did nothing for me. I thought you might be using a system restore, instead, which might mean something similar is stuck in Windows.
