The ROLL BACK method is to go to your system properties and then device
manager then the device driver and the properties for the driver then the
driver tab and select rollback driver to a previous version. You do not say
whether your sound was working properly prior to the update as well as to
what operating system that you have. If your sound was working then the
driver will be there to roll back to if not you should go to your motherboard
mfg web site to get the latest driver for your onboard sound if its a stand
alone card you should go to the mfg web site and search there. Of cource you
could always Google search for C Media that will get lots of results.
Can you be more specific about the system in question?
