Hello,
thanks for the work on PulseAudio! I would like to ask a question, and
will try to be as precise as I my limited knowledge allows.
I would like to capture the audio on the PCM channel, i.e., the mixed
sound stream that is sent to my notebook's speakers. I have read in
forums that Windows Vista achieves the behaviour I am aiming at by
offering a virtual audio channel called "what you hear" among the list
of capture sources.
Yeah pulse does this automatically. Every output device (or sink) has a
"monitor" source.
Sources are just pulses way of saying "input device", so recording from
the mic or line in or a "monitor source" is exactly the same.
So if your app is implementing direct pulse support, you can easily
record from these montitor sources. You can see the sources in
pavucontrol under the "Input Devices" tab provided you pick the right
drop down.
