How do I remove an unused audio driver?

In my System Preferences under Sound, I have an old device option showing up under Output for "Epson Projector Audio". It's several years old and stems from a meeting I attended where there was an Epson projector with a wireless display interface. You had to install software from a USB drive to use it (circa 2010).


Every once in a while, my sound defaults to this and I get no sound output until I go into preferences and change it back. It also shows up as an input option under sound as well. There is no "+/-" button to add or remove these drivers in the preferences pane so I am sure I must go and manually remove the files associated with them. I have searched for any file named Epson*.* but can't find any.


Can someone tell me how to remove these drivers?


Thanks a million!

MacBook Pro, IMac, Mac Mini, etc., Mac OS X (10.4.8)

Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library/Audio. See if the driver is there.


Also check the hard drive level Library/Audio.
