mplayer crashing (audio problem?)

[rellik]

I have the warty running on a machine here, and I'm trying to get
mplayer to work.  With the default /etc/mplayer/mplayer.conf in place, I
would get this error:

######pasted output######

I had to comment out almost all the options in /etc/mplayer/mplayer.conf
before I could get rid of the "Illegal instruction".  I left in
"ao=alsa" but everything else seemed to give that "Illegal Instruction"
error.

but still it wouldn't work.  Here's the output I'm getting now:

MPlayer interrupted by signal 4 in module: play_audio
- MPlayer crashed by an 'Illegal Instruction'.
  It usually happens when you run it on a CPU different than the one it
was
  compiled/optimized for.
  Verify this!
- MPlayer crashed by bad usage of CPU/FPU/RAM.
  Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
  disassembly. Details in
DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
  It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
  gcc version. If you think it's MPlayer's fault, please read
  DOCS/HTML/en/bugreports.html and follow the instructions there. We
can't and
  won't help unless you provide this information when reporting a
possible bug.

so it looks like there is a problem with the audio..  I'm using all the
default audio config settings for ubuntu (I haven't messed with it).
when I uncommented the "nosound = 1" line in the mplayer.conf file, I
got the first error again ("Illegal Instruction"), so I couldn't try the
file with no sound.

I'm out of ideas on this one, but if anyone out there can help that
would be much appreciated :)
