Ubuntu No Sound problem fixing

If a terminal (gnome-terminal or xterm whatever is available) type:

aplay -l

If you see this:

aplay: device_list:221: no soundcard found...

Then type

sudo aplay -l

The output of that command should look something like this:

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC861VD Analog [ALC861VD Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

It means your sound card is okay and your problem may solve easily by adding your username into audio group. Now type

grep ^audio /etc/group

to check if your username is there, if not add it:

sudo addgroup <username> audio

 <username> will be your login name ( whoami or w will reveal your username if you are not sure)

You can also do:

sudo addgroup `whoami` audio

 Note the inverted single quote ( ` ), it is crucial.
