I am using the Pi model 2 headless with Csound and a USB sound setup.
Had no problem with a cheap C-Media USB card, but with my Scarlett 2i2 the input sound is terrible (noisy, weak etc)
I must say I do not use a powered USB hub, but I do have a 2A power supply and even a small midi keyboard attached via USB. The problem also exists if I disconnect the midi device.
Output sound is no problem here!
Only when I use input, like
I get the very bad sound.

Tried all available tricks (I think), but no luck yet.
