The slicer block is expecting a floating point value from -3.0 to 3.0.
 Normally, this is the audio from an FM demodulator block that has the
deviation set so the output is in this range.  In your case, you'll
have to adjust your audio amplitude to match.  You could do this with
an AGC block, or use a scaling multiplier and set your volume control
just so.
