Clearing the CMOS resets the BIOS to their default settings. You shouldn't lose any functionality with other devices unless you changed any settings in the BIOS in order to get a certain device working properly. If you haven't changed any settings then clearing the CMOS most likely will not help since the BIOS settings are most likely the default settings.

By clearing the CMOS, will I lose access to other installed devices as well?
My wife has spent about a day and a half getting her plotter to play nice
with AutoCad, and I'd hate to lose all that work.

Try going into Device Manager and uninstalling all of the audio and
media-related items. Then, shut down.
Disconnect the power, Open the case, remove the battery and clear the CMOS.
If you can't find the CMOS CLEAR jumper (the link below IIRC has a tab for
documentation) leave the battery out for a couple of hours. Put the
battery back in, put it all back together, and restart. The system will
redetect hardware.
Reinstall the drivers starting at the lowest level you can find, and adding
higher layers.
As you probably know drivers can be found here:
http://downloadcenter.intel.com/Product_Filter.aspx?ProductID=2839
If that doesn't work, try running the Belarc free system audit. Its
detection may give you clues as to why the drivers aren't working - it may
list different hardware.
