Intermittent robotic sound defect.
Every so often the sound becomes robotic-like, it's not coming from computer internal speakers alone, it happens even when connected to external devices. The noise is like a robotic sound that's dragged out from original sound, and then it goes back to normal. I called a Dell rep and asked what was the problem, the wouldn't tell me what the problem was, but said it would take $199 to fix.
Questa è una buona domanda?
