I haven't tried this so I don't know if this will work.
In the Archicad program folder you will see a SOUNDS folder.
In there are all the sound (WAV) files.
Maybe you could try renaming / moving / deleting the ones you don't want to here and leave just the two files starting with "ACTW" - I assume this means Archicad Team Work.
