by looking at the source code a little bit, I fixed the problem by adding the
line
ao_data.channels = channels
to the start of the init() function in ao_oss.c (I put it in line 98).
Currently, ao_data.channels only gets set if (format != AFMT_AC3), so it was
being initialized to 0. (or so it appears). I don't know the code intimately,
so I don't know if my fix has any adverse side effects. Can someone more
knowledgeable let me know what's going on here, and what's supposed to be going
on here?
THanks,

MPlayer interrupted by signal 8 in module: ao2_init
- MPlayer crashed by bad usage of CPU/FPU/RAM. Recompile MPlayer with
--enable-debug and make a 'gdb' backtrace and disassembly. For details, see
DOCS/bugreports.html section 5.b.
- 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/bugreports.html and follow instructions there. We can't
and won't help unless you provide these informations when reporting a possible
bug.

See if -af-adv force=1 fixes it. The problem should be fixed before
too long anyway tho if it's what I think it is. BTW always include
full logs in addition to the gdb output; otherwise we have to just
guess what's happening.
