Status changed to 'Confirmed' because the bug affects multiple users.

This is also happening to me, 14.04 with 3.13.0-53-generic kernel.

Output from $ pacmd list-sinks attached.

I can hear sound, and the left/right channels work correctly, but any sound that comes through is crackling/robotic. I have the FiiO E17K connected via USB.

I have just restarted, keeping the FiiO plugged in, and everything seems to be working now.
