For some games (HomeWorld 1.05 being the one I'm working on), a hang occurs where the system thrashes on an ioctl SNDCTL_GETOSPACE returning with 0 fragments available. The symptom went away when I turned on --debugmsg +wave, so it seems to be some kind of race.
I've introduced a usleep(100); before returning FALSE when there are no fragments available. This seems to fix the problem.
I'm not overly happy with this solution and I'm examining the code with an eye to using poll/select to handle this more efficiently. Any comments?
there's already a wait operation in wodPlayer, so writeFragments shouldn't do any delay there may be a race somewhere, but this is not the way to fix it. are you sure that the 0 fragment is the cause of your issues ? (and not between the sender of wavehdr and the playback thread ?)
