Only you know if this is something you can do yourself.
If you are
comfortable opening your computer and working with the hardware, this
is a very simple process.
1. Have a known-working sound card on hand. If you don't have an extra
one lying around, buy one. You can buy a basic sound card for under
$20usd.
2. Check in Add/Remove Programs to see if there are any entries for the
C-Media in case it came with an uninstaller; it probably didn't but it
never hurts to check. Then go to Device Manager, find the entry for
C-Media, right-click it and choose Uninstall. Don't reboot but rather
shut down the computer.
3. With the computer turned off and unplugged, open the case. Touch a
metal part of the case (or the power supply) to ground yourself. Remove
the old sound card and replace it with the new one.
4. Restart the computer and Windows will find the new card - install it
per the card mftr.'s instructions.
If that fixes the issue, then discard the old card and keep the new one.
