I am channeling everything to the S/PDIF output on this card, but when I attempt to send AC3 it doesn't play anything. Here is the output I get from using mplayer and hits from a previous post to this list: ========================= MPlayer dev-SVN-rUNKNOWN-4.1.1 (C) 2000-2006 MPlayer Team CPU: Intel(R) Pentium(R) 4 CPU 2.40GHz (Family: 15, Model: 2, Stepping: 7) CPUflags: MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1 Compiled with runtime CPU detection.
