These values are very device dependant. For instance, mixer vol does nothing 
if I plugin the headphone on this laptop, I should use mixer ogain for the 
headphone. ogain, vol, speaker are all output volume controllers and pcm is 
for volume control for the input stream, generated by the computer.
So try ogain and speaker and see if they work for you.
