Can you try Uninstalling and Reinstalling the Audio Driver,
Open Device Manager and look under sound and gaming controller for WIN7 and Audio input for WIN8/8.1
Look for something says Conexant, and uninstall it.
Place a check if you're prompted of "Delete driver software for this device"
Then install a audio driver from this download link of your system and install it.
See if that works,
If not then, Im thinking a connection problem of the Speakers,
You can check your system's Maintenance Manual to check on how to get access to the speaker cables connecting to the Mainboard on page (52).
Hope this helps
