Thanks for all the advice. So far no luck. Specifically;
turning off the sound-at-startup option in DrakConf had no effect after
rebooting. That is, sound was not started, but mpg123 still gave the same
"device busy" error. (which makes me wonder - if sound still works without
the sound service starting at boot time, what is the point of starting it
at boot?)
ls /pro/*/fd | egrep 'dsp|fd:' showed no processes using /dev/dsp
likewise, no luck with lsof. Lots of output (duh) but nothing involving
sound.
is it possible that mpg123 is trying to use some other, non-existent sound
device or something along those lines?
btw, I used mp3tovorbis - which says it depends on mpg123 - on a file and
it worked just fine. (So at least we know that it does work).
