i've looked into the code of mpg321 and libao2 to found out the problem.
em....
after libao2 upgrade, it changes alsa09 to alsa and changes alsa to alsa05
so we have to do the corresponding modify in mpg321's source code...
for example:
we have to change
driver_id = ao_driver_id("alsa")
to
driver_id = ao_driver_id("alsa05"),
change
driver_id = ao_driver_id("alsa09")
to
driver_id = ao_driver_id("alsa")
change
strcmp(devicename, "alsa")
to
strcmp(devicename, "alsa05")
......
......
i modified and compiled the code and it works happily now with my
second sound card.

it is said that libao2 has changed alsa api after version 0.8.6.
"the 'alsa' device now uses the 0.9/1.0 api, alsa driver fixes"
is it the reason why we can't choose another sound device with -a option?
