 +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 install alsa-utils
 +open ALSO mixer:
 +  $ alsamixer
 +with F6 select the soundcard.\\
 +Test the Sound Card Output:
 +  $ speaker-test -Dplughw:1,0 -c2 -tsine
 +  $ speaker-test -Dplughw:1,0 -c2 -twav
