Hardware mixer controls != playback controls !!!
Alsamixer accesses the hardware mixer of the soundcards/-devices. And most
USB-devices don't have a hardware mixer. At least it is not accessible via
software, just via the "hands on" hardware access :-)
Which is actually a good thing because its one place less where the volume set
to zero/mute gives you endless fights of getting sound of the speakers...
