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;

Code:
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.

Android-x86 KitKat 4.4.4 Build 8 with GAPPS, kernel 4.0.9-exton-android-x86, Bluetooth (working!) and Mesa 10.5.9

Posted 01-26-2016 at 10:11 AM by exton (Exton's Blog)

Android-x86 KitKat 4.4.4 Exton Build 160125, version 8, is a ready!

Ive added Mesa (3D Graphics Library) 10.5.9 for better Graphics performance. The system can run live (from CD or a USB stick) on almost all laptops (and some Desktop computers). For example Acer (Aspire), HP, Samsung, Dell, Toshiba, Lenovo, Thinkpad, Fujitsu, Panasonic and Ausus laptops. The Android system is distributed in the form of an ISO file as the rest of my Linux distributions. I.e. you must (as usual) burn...

It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization.

NEWS 20160123 ABOUT exGENT
I've made yet a new version (20160123) of exGENT based on Gentoo Linux. Now with Xfce 4.12.1 and kernel 4.4. It's for the 64 bit architecture. I call it exGENT 2016 Xfce4 Live DVD. It replaces version 20141227. The ISO file is of 2280 MB due to the fact that this version has a lot of packages pre-installed. Among them two different Web Browsers: Firefox and Opera. Despite this exGENT version 160123 runs surprisingly fast from DVD or USB. Even in VirtualBox. Faster...

RIP x86

I've had a goofy x86 pizza box for over a decade, some early PIII with 256 MB RAM. It has a couple of odd features, namely it boots off of CF and has dual on-board NICs, that made it a nice firewall machine. I got it when the ISP next door to the company I was working at went out of business, and the network guys didn't feel like hauling all the gear off.

Only problem is, it is the only 32 bit machine in my inventory, and I've been putting off upgrading it. Luck has it, fate chose...
