i haw some usb devices reporting wrong info. Usually you can't do
anything about it in pulse, it should be done on alsa site. Here is one
of patches i did for my HW:

the problem you havem, is wrong number of mixer steps, some steps/levels
are just not working (becouse of buggy firmware). We should overwrite
the lowest level.
