I have a PC running on windows 10 sharing video files by local network to read them on my Sharp TV that has Roku build in. Everything was working just fine a few weeks ago. But yesterday when I opened a file on my "smart" TV, there was no audio coming through. I tried to open the same file with my laptop (windows 10) still by network sharing from my original PC and still no sound was coming out either, even though the file works just fine on my PC. When transferring the file on a flash drive then plugging it in both my TV and laptop it works fine too.
