Understanding mixer is not hard. PCM means "Pulse Code Mudulation" and you
can obtain more information about it from
http://en.wikipedia.org/wiki/PCM. Basically PCM is the digital coded form
of the sound that you here so computer can play with it. Generally PCM is
the where all sound signal is combined so it acts like "master". The green
lights mean active. So if a green light is turned off for a channel, that
channel is muted. Similarly red lights in input tab means "Recording this
You can say kmix to play with which slider in single slider mode (i.e.
single click, tray mode or the mode problematic for you). You need the
select the PCM since it's the master. Just right-click to the mixer icon
and select "select master channel" and select PCM from the appeared window
and select OK. Now your misbehaving slider will control your master out.
Quicktip: mouse wheel on kmix icon also commands the single slider that
ypu selected as master. No clicks needed
