-update:+ 
 +---- 
 +==== Soundcard ==== 
 + 
 +check the soundcard: 
 +  $ cat /proc/asound/modules 
 +and  
 +  $ cat /proc/asound/cards 
 +that could look like that: 
 +  0 [ALSA           ]: bcm2835_alsa - bcm2835 ALSA 
 +                      bcm2835 ALSA 
 +  1 [K6             ]: USB-Audio - Komplete Audio 6 
 +                      Native Instruments Komplete Audio 6 at usb-3f980000.usb-1.5, high speed 
 +The ALSA Card ID is 0 and the USB-Audio Card ID is 1\\ 
 + 
 +Identify the Soundcard Chip's Device ID 
 +  $ ls /proc/asound 
 +gives: 
 +  ALSA  card0  card1  cards  devices  hwdep  K6  modules  pcm  seq  timers  version 
 +means there are two sound cards 0 and 1 
 +  $ ls /proc/asound/card1 
 +gives: 
 +  id  midi0  pcm0c  pcm0p  stream0  usbbus  usbid  usbmixer 
 +Identify the device id: 
 +  $ cat /proc/asound/card1/pcm0c/info 
 +give: 
 +  card: 1 
 +  device: 0 
 +  subdevice: 0 
 +  stream: CAPTURE 
 +  id: USB Audio 
 +  name: USB Audio 
 +  subname: subdevice #0 
 +  class: 0 
 +  subclass: 0 
 +  subdevices_count: 1 
 +  subdevices_avail: 1 
 +and: 
 +  $ cat /proc/asound/card1/pcm0p/info 
 +gives: 
 +  card: 1 
 +  device: 0 
 +  subdevice: 0 
 +  stream: PLAYBACK 
 +  id: USB Audio 
 +  name: USB Audio 
 +  subname: subdevice #0 
 +  class: 0 
 +  subclass: 0 
 +  subdevices_count: 1 
 +  subdevices_avail: 1 
 +therefore in both cases the ID is 0.\\ 
 +Install ALSA utilities:
   $ sudo apt-get update   $ sudo apt-get update
-install icecast2 and darkice: +  $ sudo apt-get install alsa-utils 
-  $ sudo apt-get install icecast2 darkice +open ALSO mixer: 
-if asked type in hostname and password +  $ alsamixer 
-  hostname: localhost +with F6 select the soundcard.\\ 
-  password: ????+Test the Sound Card Output: 
 +  $ speaker-test -Dplughw:1,0 -c2 -tsine 
 +  $ speaker-test -Dplughw:1,0 -c2 -twav 
 + 
 + 
 +---- 
 +==== Darkice ==== 
 +Install Darkice.\\  
 +update: 
 +  $ sudo apt-get update  
 +get the files and install them: 
 +  $ wget https://github.com/x20mar/darkice-with-mp3-for-raspberry-pi/blob/master/darkice_1.0.1-999~mp3+1_armhf.deb?raw=true
