 Hi,

 i'm very new when it comes to LAVFilters. I'm trying to watch a PS2 Video
 using MPC-HC and i'm unable to hear the sound of the Video. According to
 the MPC-HC developer

     Audio is not recognized by LAV Filters. So issue with FFmpeg.

 Using another Videoplayer called "MPC-BE" i can hear sound while playing
