perhaps yes -- don't you have any kernel error messages regarding
this? 
could you compile the alsa-driver with --with-debug=detect?  it will
give you more verbose debug messages.

i need the kernel error messages to know whether the parameters of
these mixer elements are correct, or whether the bug is in the usb
controller module.
