JMix
====
JMix is a simple class library for manipulating mixer devices on a Linux
system under Java. I know we should really do this kind of stuff using
JavaSound/JMF these days, but the standard Linux implementations are
rarely any good, and they are really fiddly to use. This implementation
is really simple.

Installation
============
Type `make' to build everything. The shared library libjmix.so needs
to be copied somewhere where it can be found by the Java VM when
running (e.g. the JRE lib directory, typically $JAVA_HOME/jre/lib/i386)
The JAR file jmix.jar needs to be on the CLASSPATH. 

Use
===
Should be self-explanatory. Any operation has three steps:
1. open the device
2. do something
3. close the device

Opening occurs automatically when you create a new instance of the
Mixer class. Call its close() method when finished.

To find the number of mixer channels, use getNumChannels(). To find
the name of a channel, use getChannelName(). The various
get and set methods can be used to get and set the volumn, pan, etc.,
for the various channels.

Notes
=====
1. In general, channel 0 is the master volume. 
2. It is system-dependent whether the JVM gets a lock on the mixer
device while it is open. Therefore, do be sure to close() after
use.
