I am also affected by this bug. After changing the master channel to speaker in kmix, the mute button works ok. The volume up/down buttons don't work. Assigning shift+XF86Audio*Volume in kmix let's me control the volume with shift + volume buttons.
My laptop is a Lenovo 3000 V100. Output of amixer is attached.
