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...

Have fun,
