Performa: No Volume Control With Some Applications (2/96)

I have a Macintosh Performa computer, which included Sesame Street Numbers and Power Pete in the software bundle. However, I have noticed that when I open either of these applications, I can no longer adjust the sound using the front panel volume buttons.
It appears that this symptom only occurs if the Video Startup extension is installed or active when you attempt to use either Sesame Street Numbers or Power Pete. Once you quit those applications, you can control the volume normally again.

At this time, the only way to avoid this is to disable the Video Startup extension using the Extensions Manager control panel.
