[Csnd] signal flow question

Subject	[Csnd] signal flow question
	I'm trying a slightly modified version of Michael Gogin's signal flow example, but I get no sound. The ifreq and iamp variables print normal values, but amplitudes show 0. When I comment out the 'outs' I do get sound. What is wrong here?

	The signal flow opcodes are case-sensitive with respect to names. I changed "SoundFile" to "Soundfile" throughout the file, and it worked for me.
