Are you sure you are using a 4017?

Usually a 4017 has only one clock input, a clock inhibit input and a reset input.

The 4017 will advance count with each amplifier output signal strong enough to clock the chip, hence it won't be a an audio level indicator.

I suggest to take a look at the LM3915, a logarithmic version of the LM3914.
