You need a softsynth to play back midi files. Get Timidity and a nice gui
for it.
For more interesting stuff, check zynaddsubfx and specimen.

Do you have an audio cable from your cd player to your soundcard?
If not then you need a program that 'rips' the cd as it plays. There are
plenty around. I normally rip the cd with cdparanoia and keep it on the
computer.
If you do have an audio cable, then one of the many mysterious
entries in alsa mixer is muted/turned down. Kmix might not show the slider
so... Try alsamixer from the command line, play a cd, and turn up
everything you can find till it works.

I don't know anything about vmware. But at a guess...
Do you have oss compatability loaded? (Check the snd-pcm-oss module is
loaded) that's the module that provides /dev/dsp.
Also, I hope you are not trying to do audio work in a virtual machine,
it's never going to work that great.
