Disable mmdevapi capture and update changelog

Browse Source 
Unfortunately mmdevapi does not do channel remixing or resampling, even for
capture, so the device can only be opened in the mode it's configured for.
For now, fallback to dsound or winmm to get the conversion until we can do it
ourselves.
