Cathie, to set your Realtek:
1-click on Realtek HD Audio Manager
2-click on sound manager
Thank you Mario.
I don't have the manager... those windows never come up for me, and when I use the search the computer finds no results--which is a LITLLE weird, considering all the realtek files from the internal speakers should have populated. Have I mentioned lately that I am less than fond of Windows 10?? ....okay, I managed to fix the search function enough to find one folder but again, no manager. Maybe this is something I have to download separately?
