I hate pulseaudio!  The information generated by pactl is very nearly
useless.
See if you can run alsamixer hit f6 select USB Audio and hit enter.
After that a ways down the screen there's going to be lots of m's.  try
arrowing into that mess and see if you can change those m's to u's then
take the percentages up.  You may have to use tab to navigate those
controls I normally avoid alsamixer and prefer amixer since it's simpler.
