Behringer C-1U microphone under Linux - recording level too low

If you wanted to find a good way to record good quality audio and decided to buy a Behringer C-1U (U meaning USB connector), then connected it on your Ubuntu (or other Linux distribution) only to find that the sound recording level was so low you could barely hear it, then you're almost like me. I mean, unless you have found a way to fix it, in which case you're exactly like me!   Image removed.
