I started having this problem like few weeks ago and cant fix it. Problem is when i play movies on media players (KMPlayer, VLC Media Player), i can hear sounds like music in movies, but when dialogue starts, thats just like mute, can't hear it. It sounds fine on B.S Player but on others no dialogue sound, i wanna watch on other media players cuz i don't like B.S Player. I tried everything, reinstalling programs, updating sound card drivers etc..can anyone help?
