Using a buffer size of >223 causes assertion failures, and a buffer size of <=223 works (audio plays through PulseAudio, and despite buffer underrun warnings I hear no stutter). The fixes on those upstream reports are already committed to our packages, so something else needs to be done. -- pcm_pulse.c:275: pulse_write: Assertion `pcm->last_size >= (size * pcm->frame_size)' failed.
