I don't know what happened, but for some reason, the audio in videos with AAC LC SBR PS format will not play. I got the info from MediaInfo.
I tried everything from uninstalling VLC along with preferences, Windows system restore, uninstalling and reinstalling K-Lite Codec Pack (even though I assume it doesn't directly affect VLC), installed Realtek, but still won't play the audio.
All the other players I have installed plays the audio in those videos.
