How to listen to microphone output on Linux?

Question

I would like to hear the microphone output during Skype calls. I have tried fiddling with alsamixer settings and made sure that the mike is unmuted but still cannot get to hear the mike in either headphones or speakers.

Is this achievable with alsa?

start audio microphone speaker loopback with:

pacmd load-module module-loopback latency_msec=1

add a second:

pacmd load-module module-loopback latency_msec=3000

add a third:

pacmd load-module module-loopback latency_msec=5000

stop the fun afterwards:

pacmd unload-module module-loopback

if the software is missing: apt install pavucontrol (for Debian Linuxes)

You can redirect your audio input to the output using the PulseAudio loopback module:

pactl load-module module-loopback

Look for Microphone in the playback controls, it may be muted by default. Set it's lever to high, and if your microphone configured properly you will hear sound from it in your speakers.
