hi
I've some problem with a muse pocket lt soundcard from hercules, it's an 
usb card then it use snd-usb-audio, it works in the sense that I can 
hear sound.... and it don't in the sense that my pcm volume control has 
no effect, that the 2 lines volumes are able to control 2% of the volume 
about (I can set 0% 1% 2% (about) and then all the remaining is TOO 
LOOD! or saturated)

here is what lsusb gave me :
