I want heard the video and Mic What you technically need to do is record from the mic and then play it back through some speakers. PA ships with a convenient way to do this in the form of module-loopback. It basically does this and will also resample as needed to deal with slight variations in the different device clocks involved (e.g. your mic may record at 441002 Hz and your output device may consume at 440998 Hz). Because it has to resample there may be a slight delay. But: pactl load-module module-loopback Then use pavucontrol and under the recording and playback tabs you will see a new stream. Simply move this stream to the right devices for input and output and you will be able to hear the mic on the appropriate output.
