I need to test the output of all speakers in a 5.1 system that runs 10.04 and 12.04 Ubuntu?

How do I do that?

Personally I use the command line:

List your sound card(s)

aplay -L

Test your speakers:

speaker-test -Dplug:surround51 -c6 -l1 -twav

You may also specify a speaker

speaker-test -s left-front -twav

See also

You can also test your speakers from the mixer (mixer varies with window manager)

In 12.04 use the "Test Sound" button

There is no Sound preferences "test speakers" button on 10.04 or 12.04. Speaker-test worked. – keepitsimpleengineer Jul 10 '12 at 21:50
Glad you got it working. Yes, often command line tools are easier then finding the graphical tool. HUD should help. – bodhi.zazen Jul 10 '12 at 22:06
