On Sound panel, add a "Hear mic input" option when using headphones
When you use the mic and earphone on your computer, it can be difficult to speak without hear yourself.
It would be nice to have, in audio panel, an option to ear on your earphone the sound captured by your mic. So you can still ear yourself and talk like usually.
This option need to be auto turned off when user switch to speakers to avoid Larsen effect.
I know it can be done easily with the loopback module of Pulseaudio.
