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)
Test your speakers:
You may also specify a speaker
You can also test your speakers from the mixer (mixer varies with window manager)
In 12.04 use the "Test Sound" button
