sound problem with kmix (arch linux)

[nims11]

i installed ARCH 2 days ago. i used ALSA to provide audio functionality. my PC has two output jacks- one front and one rear. it's not possible to use the rear jack as due to wire length constraints. during ALSA configuring ALSA, i had to unmute the surround option to get output out of my front jack.(which i think is weird!!)
my desktop env is KDE.
the sound is working fine but i am not able to control it using the master volume!, i have to do it by opening the mixer and then adjust the PCM slider(don't know what it means). its a hassle to adjust the volume by this multistep process.
any solution?

btw ARCH is really awesome!!
