This article is about an issue involving no sound output quality setting being available on a Power Macinstosh G3.

Symptom :

I have a Power Macintosh G3 with a DVD ROM drive and I have installed OS 8.1 onto it. When I open the Monitors and Sound Control panel, the only available sound output quality is 0.00 khz and there is no choice for sound monitoring source.

Solution :

These symptoms are very similar to those that occur when the personality card is poorly seated or malfunctioning. It may, however, be caused by the wrong CD being used to install Mac OS onto the computer. The following CDs will cause this behavior:

691-1924-A
691-1969-A
691-2042-A

The way to resolve this situation is to reinstall Mac OS from the CD that came with the computer.
