#264 need help with implementing virtual microphone with introduced delay

[andrey volodin]

Hi guys,
could you help out with the following task, please?
Given there is a web browser page,
e.g. hangouts video chat,
It is required to select an audio input device ,microphone at the selection menu.
However, it is required that the selector will take inputs from a virtual microphone,
so that hardware microphone will be mapped to the virtual microphone with introduced delay 3 seconds.
I tried to begin implementing with
sudo modprobe snd-aloop
pacmd load-module module-alsa-sink device=hw:3,1
but I never got the audio output or listed virtual microphone in the browser.
