I am writing a little app in which I need to play a WAV file based on a
value in an XML file. Various XML files are passed in with different WAV
files. I'm not including the WAVs as resources. If I call PlaySound and
use the filename approach, only part of the WAV is played (the WAVs are
big, around 32 meg each). I figured I'd try the stream approach...same
result. Can someone tell me either what magic I have to use to get a big
WAV to play via PlaySound or some other method whereby I can play a WAV
file from a console application? I need this app to work for my Christmas
light/sound display.

I don't know of any specific limitation imposed by PlaySound() but that
doesn't necessarily mean that one doesn't exist. If you post again in the
multimedia group

microsoft.public.win32.programmer.mmedia

someone there will likely know. (If you get a reply from Chris P. you hit
the jackpot<g>)

That said, it is not something easy like failing to wait for the
asynchronous playback to complete before exiting, is it?

Finally, a step up in flexibility (and complexity) is provided by the
waveform API functions - waveOutOpen() etc. You might want to look for a
sample application that uses them like this one I just found here but which
I did not scrutinize:
