   Hi,

   I just grabbed a minute or so of the file, and it works fine for me, using 
either dmix or the regular ALSA device. It sounds like the problem *might* 
be an older version of ALSA. There's been some discussion of improvements in 
the dmix implementation recently, so you might try a newer version.

   I'm using ALSA 1.0.11rc3 CVS and MPlayer CVS from last night, with an SB 
AWE64. HTH. :)

   Take care,
   Steve
