So, your audioClip elmeent's contents must be a URI (or IRI).

Some of your slashes go the wrong way and you have tried to
put a space an a URI.
Try:
<audioClip xml:base = "file:///C|/My%20Music/Sample%20Music/"
xlink:href="Highway%20Blues.wma" xlink:type="simple"
xmlns:xlink="http://www.w3.org/1999/xlink"; />

The idea of xml:base is really to say where an entity (e.g
a file) come from. You can use it on individual elements, but
you might as well just use
href="file:...."
instead as far as I can tell.
In general, though, it's better to use relative uRIs if you
want your document to be portable.

I don't know if the SAX processor you are using has any special
support for xml:base, but if it does, no, there would be a call
to get the current base, since it is inherited. If not, you
would have to keep a stack of the xml:base property for each
element, defaulting to the URI of the containing resource (file).
