A quick search through recent posts produces a plethora of users who are all having no problems at all hearing both the bubbles and the CanonGuitar.sgt on a variety of W7 setups. The conclusion therefore must be that there is something different/wrong with your system/s.
Good luck with finding out what that 'something' is.
As I have mentioned before, approximately 10% of the reports are that MA3
does not properly handle bubble sound and the default music in Windows 7.

In addition, another approximately 5% report that MA3 does not work properly on Windows 7, in various other ways.
Yes, I completely agree that if MA3 works correctly with some W7 systems, and does not work correctly with other W7 systems, then there must be something different with the systems.
