Hi pulseaudio forks,
Sorry to ask silly questions again. I need some advice from you guys.
I have a front alsa sink and a rear alsa sink, right now, I`m using
to the front alsa sink, then I want to make the pa_stream both
output to front and rear alsa sink.
Here is the pipeline before move:
pa_stream -> sink-input -> front alsa sink
What I am doing is create a new combine-sink, and make the
combine-sink connected with front and
alsa sink, then move the sink input of pa_stream from front to
Here is the pipeline after move:
-> sink-input -> front
pa_stream -> sink-input -> combine-sink
-> sink-input -> rear
I have dump all the data written to the front alsa sink, There is a
very small time of silence has been
written to front alsa sink after pa_sink_input_move_to (about 20 ms),
I think that might be the latency of
speex resampler (to adjust the rates of sink-input in combine-sink).
Do you have any advice to avoid this kind of noise ? Thanks!
