Hi,
Sorry for my delay and thanks for the reply.
I understand that I can only record one sound source and my other activities should not use sound.
I seem to be missing something else.
I got OBS started as the attached screenshot...
I tried many ways to do as you advised but I have no such option from the Scene menu at the bottom and when I do a "window capture" from the 2nd from left menu and start recording it keeps recording all the other screens and activity that I do with them
and not just the window that I started with.
I'm new to this app and need to learn more on how to work with it ...
Thanks
