the lm3916 is slightly messed up the program did not have 18 pin chip

this is two halfs of my project

induvidually the both work but
joining together im having problems

when nothing is connectted to pin 5 all leds are on
when pin 5 is connect to ground all led are off
when pin 5 is connected to top half of the output pins (one above capacitor) all leds are on
when pin 5 is connected to bottom of output pins below cap all leds off

when a 20k resistor is attached to pin 5 to ground
when nothing is connectted to pin 5 all leds are off
when pin 5 is connect to ground all led are off
when pin 5 is connected to top half of the output pins (one above capacitor) all leds are on
when pin 5 is connected to bottom of output pins below cap all leds off

what do you mean

do you mean this sentence
can someone guide me in the correct direction to get this thing working

by that i mean when pin 5 is connected somehow to microphone and amplifier
when there is silence all leds are off
and when there is noise the lights bounce up and down
