I'm not sure whether asterisk is going to fire up multiple instances or
just a single one of the player in your case, but if not you might be
able to use sox to take dsp as input and output ulaw on stdout
(e.g. define this in musiconhold.conf: sox -t ossdsp /dev/dsp -t ul -).
I kind of suspect that you will get locking problems between multiple
sox'es too, but that depends....
