it doesn't work for me either on the dingoo unfortunatly, it doesn't hang, but all i get to hear is static and hissing. while in windows i get to hear almost a perfect pacman tune. (almost because i can't get it / know how to make it sound perfect) but it doesn't work on the dingoo so i stopped messing around with it.
currently i'm upgrading my ubuntu box, to install ubuntu 9.04 and then try out the linux stuff and port some emulators for that (if i'm able too) but i think it shouldn't be too hard at least i hope so don't have much experience porting stuff but i'm willing to learn.
i'll download the sources again later today perhaps and see if i can get it partially working on the dingoo , but don't get your hopes up cause last time it just didn't work out like i expected it would.
