Here is a solution that I’ve tested with Pulse Audio on Ubuntu 12.04.
- Install PulseAudio Volume Control (
- 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
