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,
Arnold

My Zoom H2 when used as a USB devices introduces 0 controls, but I can monitor from it and record. I'm still not able to fix the latency issue I'm having there, or the fact that I hear the clean signal (going in to the computer) together with the processed one which is coming out from JACK. I just gave up because it wasn't my intention to make it do anything, just curious to see how it worked.
