Comment 2 for bug 447232

Noticed one thing: It's the control of the volume buttons in front of my Dell that's bugging out. When I started Alsa mixer and used the volume buttons, I saw that the buttons only affected the master volume. The PCM and the LFE isn't affected until master is at 0, then those two go to zero if I press the button a few more times. If I use the lever for PCM in the alsa mixer, I can adjust the playback volume just the way it should work with the frontal buttons.
