I can play quite a few sounds with no problem and then after a while (*possibly* related to pressing keys at just the wrong time?) no sound but the system is otherwise OK. Then after a while it locks up the VM completely.
Turning on debugging printfs in the vm-sound-pulse/SqUnixSoundPulseAudio.c file provides a minimally interesting log that finally reports
DBG: sqUnixSoundMaemo: >sound_Stop() (11, Resource temporarily unavailable)
though one must note that this DBG comes at the beginning of the routine and thus seems to require errno to have been set non-0 just before.
Attempts at asking Lt.Cmdr.Google for suggested pages mostly implied that that error message is rather annoyingly generic, though plenty of people seem to have seen it because of pulse audio problems.
Pointers to actually meaningful references would be appreciated.
