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.
