Summary:                    Clicks or pops are produced in Griffin USB iMic PCM
output
Description: 
I've been spending the longest time trying to figure out why FluidSynth has
been producing these inconsistent clicks while I play MIDI through it. I
finally determined that this behaviour is not specific to FluidSynth, but
to my USB iMic sound card, since the problem does not occur when I
configure FluidSynth to use my internal sound card. I am also able to hear
these clicks through the iMic by just playing an MP3 through them,
although it's not as frequent. It seems that the frequency of the clicks
is dependent on my CPU load; the more I stress my system, the easier it is
to hear these clicks/pops. But it's difficult to determine whether there's
a direct relationship there or not, because this behaviour is so
inconsistent. But I can always cause the clicks to happen within at most a
couple minutes, especially if I'm playing MIDI through FluidSynth.
