I have a working 1998 Power Macintosh M3 Model M3979, and the sound suddenly went to a level zero. I used help to open the sound settings and when I slide the sound level up, there is a flash in the top of the window that basically says "nope!" and the slider goes back to zero instantly. Anyone know what might cause this, or how to fix it?
Thank you in advance.
