Sound Cutting out during show

This problem is just starting to happen but it is becoming more and more frequent.  When we run the show, the sound seems to cut out, but the lights continue.  When the music comes back, it comes back at the point it cut out.  It doesn't loose any of the song.  When I go to task manager and watch performance, during the time the sound is out, it spikes and stays up there 2-3 seconds.  Most of the time the computer performance is running 40-50%.  If I watch processes, it will show the sequencer running and when the show stops scheduler will pop up in the processes and then another sequencer will start.  Sometimes it will show 2 sequencers running at the same time.  The performance is really high during that time.  Then slowly one will go down and go away until another song starts.  It doesn't seem to matter if it is a wave or MP3 file.  I am running vista with aurora v1.032. 

Only time I ever had anything like this is when I used MP3s, but you said that you have it even when the song uses WAVs. Are you sure that the sequence was updated with the WAV and it was re-saved so that it really knows to use the WAV?

That's still the exact same thing that mine did with the MP3s.

I have to second the MP3 statement by PG. In my learning experiments with Halloween I used MP3 and had that issue.  It went away when I converted to WAV.  I had the issue on multiple machine types.  All gone when I converted.
