I have tried all of these. I don't know what this code stands for when I do the device manager and click on the Realtex link, maybe it means something to you.

This device cannot start. (Code 10)

The policy object does not exist when it should

I wanted to let you and everyone know I finally got my issue with no sound resolved. Thank you for all your help. I wanted to mention what I did in case someone else is having the same problem.

I was finally able to find the update that switched my system from 24h2 to 25h2 and I uninstalled it. I shut down my computer and restarted it, then ran an update again. The update reinstalled the update that caused the problem in the first place but somehow it fixed the issues. It took me a long time doing all the suggestions you advised with no luck. I hope this helps someone else if they have this issues. Thanks again.
