I'm having a problem with the internal speaker (not system beep!) of my Optiplex 380 Mini Towers.
The machines came without internal speaker, so I connected the ones from my old Optiplex 360 machines (same connector, same method of clipping them on the chassis). But they only give me a "clicking" sound followed by the actual sound in a almost not audible volume, even if volume is on max.
The speakers themselves are ok, tested them in 360 machines and they are working fine.
