The speakers on my transformer book don't work. When I go to the Control Panel->Sound there's nothing coming through to the speakers. The graph to the right of the listing for the speakers doesn't move, so the speakers aren't getting anything from the web browsers or media players.

When I plug speakers into the jack port the control panel doesn't recognise that anything is plugged into the port.

I've checked the device drivers and my system is saying that it has the most current drivers.

I uninstalled all the sound devices from the device manager then checked for hardware changes and it looked like the device manager reinstalled all the sound devices and the drivers and nothing has changed.

I just can't get any sound out of my laptop.

Short of trying to refresh the os, is there something I can do to fix this?
