Hi, I have royally screwed things up with my computer, thanks to the Windows 10 free upgrade, which I am regretting.
1. After the upgrade the sound didn't work but I found some instructions, and those worked. So far, so good.
2. Recently it auto-updated. The sound went out again. I SHOULD have done a rollback, but did not. Then I tried to update the Realtek Audio HD drivers. I updated to the latest 64-bit driver. (That was probably the wrong one, because it didn't work).
3. Then I uninstalled the Realtek drivers. Apparently, I even deleted the RealTek HD Audio device as well. At that point Rollback would not work.
4. Now, in Device Manager, under "Sound, Video and Game Controllers" this is what you see (attached).
Can someone help me fix this machine?
