You could try to run finale in wine -> jack-bridge -> jack

If you are using jack2 it will disable pulse audio when jack is started. 
Not sure what the default is on ubuntu karmic.

You can also turn off pulseaudio temporarily with "pulseaudio -k"

However it might autospawn in which case you will need to disable that 
by editing /etc/pulse/client.conf and changing "autospawn = yes" on line 
26 to "autospawn = no"

then of course you will need to set the audio output in vmware to alsa 
instead of pulse and you will need to check the default sound device is 
set to hw:0 instead of pulse. You can force it by editing /etc/asound.conf
