That's what mplayer says:

Opening audio decoder: [ffmpeg] FFmpeg/libavcodec audio decoders
AUDIO: 48000 Hz, 6 ch, s16le, 448.0 kbit/9.72% (ratio: 56000->576000)
Selected audio codec: [ffac3] afm: ffmpeg (FFmpeg AC-3)
AO: [oss] 48000Hz 6ch s16le (2 bytes per sample)

What do you mean by "a decoder is needed"?
