In the $Path or not using Mathematica 4.2 Windows 2000
 I did the following:

In[1]:=
Import["C:\\Documents and Settings\\hans\\My Documents\\raymond.wav", "WAV"]
Out[1]=
\[SkeletonIndicator]Sound\[SkeletonIndicator]

Note the double \\

It returned a Sound object
Sound[SampledSoundList[data, r]]

Which can be displayed using Show[%].

And played by double clicking on the graphics.

This is fast

Alternately you can load the add-on
In[2]:=
<< Miscellaneous`Audio`
In[3]:=
ReadSoundfile["C:\\Documents and Settings\\hans\My Documents\\raymond.wav",
PrintHeader->True]

Then use ListPlay

In[4]:=
ListPlay[%, SampleRate->22050, PlayRange->{-2^15,2^15}]

This is slow.

In the ReadSoundFile you can see the data.

With Import use FullForm on the Sound object to see the Format. Then grab
the List (data).
