GNU/Linux with GNOME and has a Sound Blaster card. You will
notice that some channels are stereo while others are mono.
For each stereo channel there is a
Lock button which ensures that the
right and left channel will have the same gain. You will
also notice that there are mute
buttons to completely ignore a certain channel.

might want to make sure that sound is properly configured
for you. With older versions of Linux you might have to
re-configure and build the kernel with support for your
sound card. With recent distributions (such as Red Hat
5.x) you can run <B
