Enabling surround sound in ubuntu

After a lot of attempts (edit files, up and down volume controls) I could enable sound in Ubuntu. To do this, I made the next:

1. Re-install alsa-utils. I think that this is not necessary.
2. Open volumen controls. (Alsa Mixer)
3. Preferences, and check “Channel Mode”. This will visible a TAB “Options”, here you must select “6ch” and ready.

To test your surround system, you can write into Console:

speaker-test -Dplug:surround51 -c6 -l1 -twav
and this will allow listen a voice for every speaker.

root@konunantulinux:~# speaker-test -Dplug:surround51 -c6 -l1 -twav
speaker-test 1.0.15
Playback device is plug:surround51
Stream parameters are 48000Hz, S16_LE, 6 channels
WAV file(s)
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 16384
Period size range from 32 to 8192
Using max buffer size 16384
Periods = 4
was set period_size = 4096
was set buffer_size = 16384
0 - Front Left
4 - Center
1 - Front Right
3 - Rear Right
2 - Rear Left
5 - LFE
Time per period = 8.449852

To know your sound card, you can write:
root@konunantulinux:~# sudo asoundconf list
Please note that you are attempting to run asoundconf as a privileged superuser, which may have unintended consequences.
Names of available sound cards:
VT82xx


In this case, VT82xx is my card.

My surround system is a Genius SW-5.1 100

Good Luck. :)
