My Samson G Track Pro USB mic is too quiet. It's detected and I can record with it, but I have no input level/gain control in the interface. All controls are on the mic, itself. Even if I crank the mic's gain all the way, the waveform recorded is tiny. Through the mic's built-in monitor, the levels are nice and powerful. I've taken a look around for answers, but it seems the problems are pretty specific to each USB mic. Clearly, there's something (if anything) that has to be done on the Linux/ALSA/PulseAudio side of things.
Here's some information:
