[pulseaudio-discuss] Couple of PA problems

[Alexey Fisher]

Hi James,

please do not start any bug report with frustration or comparision to
windows, it frustrate devs.

To your problem. PA do not route IN to OUT, you can force it like
"gst-launch pulsesrc ! pulsesink" but you really don't wont it.

I'm sure to 99%, your problem is hardware. Take a look to some deeper
layer like ALSA (HW -> ALSA -> PA -> ALSA -> HW). Start "alsamixer" and
take look to some thing with name "Mic" or "Line in" and mute it. In
alsamixer you will have 3 section: playback, input, all. In playbak
section "Mic" is monitor for your microphone. This will actually route
your mic to speakers directly.

If sound from the laptop's built-in microphone pollutes the output audio stream, that's completely unacceptable. (OTOH, Jack suspends PA and this might stop the unwanted routing. I hope... I don't remember exactly, will check later.)
