ffmpeg alsa recording multiple applications audio

The trick is using dmix on loopback device:
2 dmixers; one for regualr onboard audio; the other for loopback virtual device, then duplicates streams send to onboard audio card, so you can hear what is being sent to loopback device.

Need to load snd_aloop module first;

modprobe snd-aloop index=2 id=Loopback pcm_substreams=1 enable=1
My first audio device is onboard soundcard; 2nd is HDMI card, so I put index=2 for Loopback device.

When you copy and paste these code into your /etc/issue with your vi or vim, you might need to replace ^[ with Control+V then Control+[ in input mode.

^[[0;32m   _____    ^[[0;34m _                  _
^[[0;32m  / ____|   ^[[0;34m| |                | |
^[[0;32m | (___     ^[[0;34m| |   __ _    ___  | | __ ^[[0;33m__      __   __ _   _ __    ^[[0;35m___
