Dell duo station
I had the same issue. I tried opening the dock and could not find anything wrong. It seems the charger was delivering sufficient voltage. So I disconnected power to the charger and reconnected couple of times and it started working again. My charger has a LED light and based on the brightness of the light you can findout if the output voltage is close to 20 volts.

Background noise recording with dell
Get a wired lapel microphone and plug it into the microphone input on your Dell. The onboard mic is designed to record all ambient sounds. You want a different product to get the result you're looking for.
How can I fix the sound on my Windows 7 computer
Try plugging a pair of headphones or earbuds or a different pair of known-working speakers (in places of the current speakers) - if you get sound with the "replacements", then there's a problem with the "current" speakers; otherwise, the problem is the sound on the unit.
Alternatively, plug the "current" speakers into a different (preferably, known-working) unit. If there's still no sound, then there's a problem with the speakers; otherwise, the problem is the sound on the original unit.
