When this computer is upgraded to Windows 10, the Beatsaudio that was built in becomes incompatible. I beleive I have found the solution.
Go to the Realtec website and find under drivers the following driver named:
Read the memo 'Read Me' pdf
0008-Win7_Win81_Win10_R282.exe or the same in a zip file.
Down load the above driver to your Downloads
Go to the Divice Manager.
Select the Sound, video and game icon.
Delete the current Realtec Audio driver.
Run the downloaded driver as Administrator
If you get an incompatible error, install anyway
Wait till the troubleshooter checks your system
Reboot the computer
Try the audio.
If not sucessfully install, go back to the Realtec site and download the same in a zip file and start again.
