--- Comment #29 from Raymond <superquad.vortex2 at gmail.com> ---

pulseaudio need to provide debug info about the number of frames written when
it call snd_pcm_start

since work_done must be at least the size of fifo buffer or twice the dma brust
size 


/*             pa_log_debug("work_done = %i", work_done); */

            if (work_done) {

                if (u->first) {
-                    pa_log_info("Starting playback.");
+                    pa_log_info("Starting playback %d ", work_done);
                    snd_pcm_start(u->pcm_handle);

                    pa_smoother_resume(u->smoother, pa_rtclock_now(), true);

                    u->first = false;
                }

                update_smoother(u);
            }
