[SOLVED] sound in players independent of volume control buttons in gutsy

[vamsibethapudy]

i am a beginner in linux arena.
i previously used feisty for a few weeks.
then i switched to gutsy.
the problem is my laptop volume buttons dont control the volume of the applications.
i have searched for some solution in previous posts.
wat i learnt was :there are two volume options (or whatever)MASTER & PCM
my laptop buttons control only the MASTER.
the applications are controlled by PCM volume level.
i dont know how the settings were in previous feisty,but my laptop buttons could change volume of applications.
i couldn't do it in gutsy.
someone help me.
if u could explain to me what MASTER & PCM do , it would be helpful.
if there is any mistake in what i have understood & stated above please tell me.

HI !
Go to "System > Preferences > Sound" and change under "Default Mixer Tracks" from "Master Mono" to "PCM"

I don't know what are the differences between PCM and Master Mono. All I know is that I re-installed my Ubuntu 5 times, before I found out what's the problem with my volume buttons
