Well yes and no scott.
You do have a lot of sound options you can mess with in wow and i played around with them a bit just out of curiousity to see if any of them would affect the CD sound. Here are the results.
Nothing in the sound options will affect the CD alert sound except for disabling sound entirely or master volume.
And the reasons why those 2 do are pretty self explanatory.
So the CD sound isnt being recognized by wow as:

1. ambience - which controls all the nice weather efects etc

2. sound - which controls sound efects like your mount running or you chomping away at food

3. music - ah the lovely music

None of the checkboxes have any efect on the sound of the CD either.

So wow is taking it as an unknown sound and playing it as is. The the only thing affecting it is the persons system, sound card, etc. I never thought to look and i guess i assumed this was a sound byte you had added yourself Scott, or is it a sound that has been borrowed from wow or users system? Ive never gotten into playing with sounds in my own dabblings.
Makes me wonder if there is a way to get wow to recognize it as belonging to one of wow's sound catagories.
