Windows prefers stereo to mono for line ins, and mono to stereo for (non-array)
microphones.
More explicitly:
For bridge pins that expose a KS node type of "KSNODETYPE_LINE_CONNECTOR",
Windows 7 will try various stereo and mono formats, preferring stereo if both
are supported.
For bridge pins that expose a KS node type of "KSNODETYPE_MICROPHONE_ARRAY",
Windows 7 will use only the "preferred format" exposed by the device and will
not probe at all.
For other capture bridge pins, Windows 7 will try various stereo and mono
formats, preferring mono if both are supported.
