[Mplayer-users] How to pipe the ac3 data through an external program like ac3play ?

I've created a avi-file with divx video and ac3 tone.
If I use the -dumpaudio option, I get a file stream.dump, which I can
play with ac3play and get dolby digital sound.

If I try to pipe the ac3 data to a file during playing the avi file, I
don't get any ac3 data (ac3play says "CRC failed").

I want to pipe this data in a pipedevice, so ac3play can play it during
watching the video.

the command I tried it:

mplayer -vo x11 -ao pcm -nowaveheader mydivx.avi

my codecs.conf

audiocodec pcm
  info "Uncompressed PCM"
  status working
;  format 0x1
;;;; these are for hardware support only:
;  format 0x6
;  format 0x7
;  format 0x11
;  format 0x50
  format 0x2000
  driver dvdpcm
  dll "uncompressed"

Does anybody have successfully get the ac3data ?

BTW.: I'm using mplayer 0.18pre5 and ac3play-0.4.0
