Mic loopback ubuntu – hear my sound through speakers


Here is a solution that I’ve tested with Pulse Audio on Ubuntu 12.04.

  • Install PulseAudio Volume Control (pavucontrol)
  • Now we will route your microphone to your speakers. Do this by running the following command:
    pactl load-module module-loopback latency_msec=1
  • On the Recording tab of pavucontrol, you can show all streams (combobox at the bottom) and then configure which microphone (if you have more than one) should loopback into the built-in analog stereo

To stop it running, run:

pactl unload-module module-loopback
