I was trying to be able to monitor my microphone input and I ran into this question. (How to hear my voice in speakers with a mic?)
I followed Charl Botha's advice, and launched pulseaudio volume control, then typed into the terminal that I used to launch the application
pactl load-module module-loopback latency_msec=1
after doing this, nothing happened except that now there is no sound at all!
I have checked all pulseaudio volume control settings and everything seems to be fine, yet there still is no sound. Guest account has sound, but mine does not.
Any help would be much appreciated!
