I wanted to add that the Designed for Windows Vista Logo program
requires 44.1KHz native sample rate support in addition to 48KHz (or in
the case of 48KHz any multiple of 48KHz is allowed instead).
If your hardware follows our Vista Logo requirements it will ensure the
best possible user experience with Windows Vista. If your hardware does
not follow the requirements your results may vary as the operating
system is optimized for compliant hardware.

That appears to be the case. We took a late change to the wmapro test
tone file (%windir%\media\wmapro.wav) and it looks like the most recent
version is 44.1KHz. It is supposed to be (and is in earlier builds)
48KHz. Unfortunately there is no way to fix this without updating the
test file.

Thanks for the reply. If I hit test buttom for WMA pro, the system shows
a warning dialog box saying it can not play the test tone and the
support for this format will be disabled. Test tones for Dolby and DTS
formats can be played correctly. From the debug log I can see that
NewStream() did not even get called when testing WMA pro. Is it because
only 48K sampling rate is supported (our SPDIF output only support 48K)?
