[pulseaudio-discuss] Bluetooth HSP sink is more likely to cause buffer underrun when moving a live stream to it from ALSA, how to ask application to write more data?

My VOIP application use GStreamer's pulsesink. But I found pulsesink does not adjust flow rate when it receives latency change or buffer underrun callbacks ;-(

But it's strange that why ALSA sink does not cause excessive underrun no matter moving sinks or not?
