I am facing a weird problem. I am shooting in my Sony Alpha DSLR camera and that saves the video format as a .MTS file. I was importing many .MTS file into the Adobe Premier Pro CC 2015 composing track, but suddenly now, all my imported files' audio track is missing. I can hear the voice or background audio of that file by opening on Windows Media Player, VLC Media Player and other players. Only, the video editing software from Adobe doesn't recognize the audio. How to fix it without downloading any third-party crap software?
