After fixing audio in windows on my laptop with your solution (thanks so much!)....I still had no audio to hdmi cable and tv display. Playback devices showed only Speakers/HP in listing. I tried adding a second display device to no avail. At one point I had Speakers/HP highlighted and showing as default, when i inadvertently right clicked on it and a menu popped up.
I t had an option to show all disabled devices , so i clicked it and Ouila! My samsung tv showed on the list as disabled. I enabled it and it set as default. Tested fine! Now my question is: Can laptop audio operate independently and at the same time as the second display audio? Just hoping my mom and I can each have our cake and eat it too.
Thanks again for your help.
