Need a little help playing WMVs. Whenever I load a WMV in any player (Mplayer, gxine, totem-xine) I hear little or no sound. For the most part, it is mute but at some points a bit of audio will play before going mute again. Video plays back just fine. AVI, MPG and all files encoded in DivX, Real, QUickTime and the like all playback fine. ANybody have any ideas on how to fix this?
