Dell Inspiron 660 Sound Issues (Issue Resolved)

(Issue has been resolved)

I have an Inspiron 660 desktop that I bought about 3.5 years ago. I updated to Windows 10 and have recently started using a Dell U2415 UltraSharp Monitor. The sound bar was working well with the new monitor and desktop until about a week ago I noticed the sound started getting low, then completely out, then came back on like normal.  It worked fine for the last week, then it started doing it again today and now completely no sound.  I have tried headphones and two different Dell sound bars and the sound doesn't work on any of them.  I have looked at settings and device manager and it says the 'Intel (R) Display Audio' is working correctly.

I have looked at different solutions, including downloaded the latest audio (Conexant Smart Audio Driver) and chip driver updates (12/15) and still no luck.  Can someone please help?
