For some reason, the sound seems to be much quieter when I play an m2ts file (has been muxed from an mkv) in WMP. It is loud and clear on VLC, but not on windows media player. I have installed ffdshow and Haali Media Splitter. The video looks fine.. the audio just seems to be the only problem.
Also.. I keep getting a C00D11B1 message.. but I don't know what's wrong with my sound card. I have the latest drivers and everything..
