Just wanted to do a follow up. I have found my issue, it has nothing to do with ZDSoft Screen Recorder settings.
Thought I would mention it in case anyone else runs into this problem.
In my case I also have a USB TV Tuner and a Web Cam installed on my PC.
What I did and what working for me : On Windows 10 latest update I had to go into
settings/system/sounds and under “Input” I changed the input sound from my USB TV Tuner to my sound card. After doing that audio and video record fine.
Everything is working as it should now.
Thanks again Ashraf and ZDSoft!
