From: Martin Schrodt <mar...@schrodt.org> The current code does not specify the metrics of the buffers for the input device. This makes PulseAudio choose very bad defaults, which causes input to be unusable: Audio put in gets out 30 seconds later. This patch fixes that and makes the latency configurable as well.
