How to get volume control back , when device manager says “” no audio device “”

I have been using MSE  for a very long time , and also IOBIT   ,, they seem to work together with no conflicts .  Iobit offered a free driver booster to update drivers , and I messed up and clicked on it thinking it would improve the overall performance of my computer .  It resulted in "" No Sounds  "" , volume control in system tray disappeared , and no sounds when playing a video.  Overall performance of computer seems to be working , until I click  microsoft updates , it will temporary shut down MSE , then turn back on , but  Microsoft Security client  will pop up saying  "" the feature your trying to use is on a network  resource that is  unavailable ""      All this happened right after installing  this driver booster ,, became discouraged and used uninstall to remove it .   How can I get this sounds back???
