I know, here's another one with no sound. Roll your eys but, please stay with me. I've been through most all the Youtubes for this subject. Have FHD Capture dongle to my 3.0 USB in my Dell Inspiron that was working great then one day I had no audio from my Dish Net tv source. Bought another one and didn't make a difference. I have Dish going through a Yamaha receiver to my tv. I split the hdmi going to the tv and ran one side to my PC so I can watch news stock reports, via OBS, on my computer. Was working fine but all of a sudden it still had nice video with no audio in my desktop speakers/headphones. If I just open something on line, I have fine audio from there, so my realteck sound is still functioning. Either an OBS update changed something or a Win10 update did. I've tried all the sound hacks on youtube. Makes no difference. Device manager doesn't even show any sound levels coming from the FHD, though it says it's working fine. Any suggestions?
