The first place to look rather then trying to remove and then reinstall would be in the Control Panel>Sound"Recording area where you can set the default device as well as run the configuration wizard.
The other thing that can be a larger help when first coming out of sleep or the hibernation mode is simply seeing a full system restart to refresh all
drivers and devices. The main problem with any device or drivers is simply remaining inactive after restoring the desktop from either of those two modes.
