[QnA] Sound volume control in command line

I've used wmii for several weeks, and it meets most of my need well. Sometimes, however, I want to control the volume but there is no the control panel as in the Gnome desktop environment.

Here is the solution: amixer (or alsamixer, which has the ncurses interface).

To use alsamixer is easier due to the straightforward interface. If you get the following error message when you type ``alsamixer'' in the command
alsamixer: function snd_ctl_open failed for default: Connection refused
then do the following steps:
$ rm ~/.asoundrc and then do
$ asoundconf list
$ asoundconf set-default-card foo
where the foo is one of the sound cards listed by `asoundconf list.'
