> I have compiled latest svn code (revision 27834) and try to use it to play a mkv container with a AC3 sound stream but mplayer does crash during init. I have used the same set of command line parameters and also played the same files in mplayer 1.0RC2 without any problem but with current svn code it always crash. When I run without the parameters "-afm hwac3 -ao alsa:noblock:device=hw=0.1" or with the parameter "-nosound" everything is running ok. Mplayer is also capable of playing a video file without AC3 without crashing. I want to get the AC3 stream to my Yamaha receiver to get true Dolby Digital 5.1 and DTS which works perfectly in Mplayer 1.0RC2 with the command line below.
