I'm stumped. I have a Samsung UN55B8000 with a wifi usb adapter and a 17" Dell Inspiron upgraded to win 10 pro 1803. I installed the Samsung Smart View app it and enabled sharing, laptop found the TV no problem, I casted a video to it no problem, clear pic, but no sound (I did trigger it briefly somehow, can't repeat) . The sound from the TV is directed to my pioneer tuner via optical, I play movies from a hard drive also plugged into the tv usb port and the audio goes to the pioneer via the optical. I upgraded sound drivers and video.So then I just try casting a music file, it plays fine. I try another video, still just picture. No fancy audio codecs or anything just mp4a: MPEG-4 AAC LC 48000Hz 96 kb/s tot , stereo (2/0) . I ran the windows troubleshooters, no help. Any more ideas?
