Example of problematic videos: watch?v=Oi-U-lzvhgo watch?v=orB4JXdIVR4 Music volume is low but there's very loud static noise covering it. Video plays in HTML5. No issue with flash player (11.2 r202). Using google-chrome 18.0.1025.168 on Ubuntu 12.04 x86. Same problem with Firefox 12 (HTML5 playback too, no issue with flash player).
