 +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

 +  subname: subdevice #0
 +  class: 0
 +  subclass: 0
 +  subdevices_count: 1
 +  subdevices_avail: 1
 +and:
 +  $ cat /proc/asound/card1/pcm0p/info
 +gives:

 +  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:
