I would like to add the following: KSNODETYPE_DIGITAL_AUDIO_INTERFACE doesnt work either. Allthough the symbol looks nicer and the type matches best. Therefore we are using a combination of KSNODETYPE_SPEAKER, KSNODETYPE_LINE_CONNECTOR and KSNODETYPE_SPDIF so far for our digital interfaces.

If I use type KSNODETYPE_ANALOG_CONNECTOR for my inputs, which worked fine
under Windows XP, it doesn't work in Windows Vista (no record device shown
in dialog).  I have to change to KSNODETYPE_LINE_CONNECTOR.  That isn't such
a big deal, but I needed to change it to get a device that worked fine under
Windows XP to appear under Windows Vista.

On the output side, I had to use type KSNODETYPE_SPEAKER in Windows XP in
order to get the "speaker" icon in the system tray that lets the user get to
the mixer.  I can change that to KSNODETYPE_LINE_CONNECTOR (or
KSNODETYPE_SPDIF_INTERFACE for digital outputs), and that makes things look
nicer in the Windows Vista control panel.  But, like I said, those node
types cause loss of functionality under Windows XP.
