Updated version of realtek rear output audio device

Solution
Your realtek drivers are located on the computer manufacturer's website, look up your machine by model number...

Your surround sound drivers may need to be downloaded from the Dolby website, check with your manufacturer. If the rear channel audio does not function, you may need surround drivers, or you may need to check the settings of the audio software. Inside the software are speaker configuration settings.

Double click the speaker icon in the lower right hand of the desktop, this will bring up the mixer, or single click to bring up the volume control.
But in case the volume is missing, corrupted, or the audio is otherwise non-functional:
you check whichever audio was installed:
click start, control panel, add remove programs...

click start, control panel, add remove programs, look at the list...
which audio software is shown on the list? delete it, restart the computer.

now visit the motherboard manufacturer or computer manufacturer's website
look up your computer drivers by model number
download the latest audio drivers, save on the desktop...
turn the antivirus off,
if you have multiple security programs installed, turn them all off
(your driver may not install if security systems are turned on)
now load your new audio driver, restart, turn the antivirus back on.
Let the forum know if that solves the problem. SGM
