How do I amplify white noise

Following a few online examples I've made Zerner noise in Every Circuit (cool!). But I'm wondering now how do you amplify a signal like this and make it bipolar for audio output?

Use op amp with high pass filter.

There is no real noise model for any Everycircuit component. Not for diodes, not for teansistors and also not for zener diodes. Tell me what amplitude of noise you see at the transistor output, collector! Nothing. pico volts??? Its just rounding errors you see in simulation steps, but its not thermal noise!!

This stopped working shortly after hurz said it was just rounding error?

https://everycircuit.com/circuit/6421341121150976 here is a general amplifier circuit. Depending on where you tap into it depends if you get voltage or amperage, it can be tuned fairly easily for signal control and the Lowpass LC Filter foundation at the bottom is the key to making just about any sound based circuit work in the EveryCircuit app from what I've seen. As far as "displaying" the sound the best your going to get is the waveform representation shown in the ocilloscope's display screen by putting three monitor traces on voltage wires and one on a component like a capacitor then use the alternative view for the capacitor trace.
