Intro
|
||||
-----
|
||||
|
||||
This is a quick mixer program for the ALSA project. It will grow out
|
||||
to include a GTK interface eventually, if noone beats me to it :)
|
||||
|
||||
|
||||
Building
|
||||
--------
|
||||
|
||||
Edit the Makefile where the -I (include option) is. This should
|
||||
point to the directory where the alsadriver is located. Then
|
||||
type "make" and it should build without complaining. If you have
|
||||
trouble with it please mail me at <arloafoe@cs.vu.nl>
|
||||
|
||||
|
||||
Running
|
||||
-------
|
||||
|
||||
amixer -h should display the syntax
|
||||
|
||||
|
||||
Bugs & Todo
|
||||
-----------
|
||||
|
||||
A lot, let me know..
|
||||
|
||||
|
||||
Changes
|
||||
-------
|
||||
|
||||
v0.001 March 20 1998 - Initial code
|
||||
v0.1 Apr 21 1997 - Actually useful now
