Whenever I try to play large mkv files (usually the in the 10-12GB range for 1080p movies) the sound is just awful. It's muddled and staticky as if there were a jet engine roaring in the background of every scene. It's usually most prominent during sound effects and music playing, and not so much with scenes of pure dialogue. I know the files themselves are good, so how to solve the problem?

VLC has known issues with DTS-HD audio. Have you tried a different audio track?

Or a different player such as CCCP Project/MPC-HC?
