Sound Manager 3.1 does not work properly on the Power 120 machines. Symptoms include lockups when opening the Sound Control Panel.
This is related to the problems with System 7.5.1, which will not run on a 120 MHz computer. If you remove the Sound Manager 3.1 extension, you will automatically be using version 3.0, which should work fine.

7.5.3 uses the newest version of Sound Manager 3.1b, and this will work fine on the Power 120's.

Machines Affected: Power 120
