You'll notice a lot of relevant stuff greyed out. I possess 2 speakers and a subwoofer, which appear to operate through a program "Turtle Beach Riviera" which is present at start up.
Multiple attempts have been made to fix the problem and get the proper settings put back on but to no avail. Repeats of these attempts are acceptable because it was so long ago I don't remember what we tried.
Any and all help is welcome!
