So, you are connecting the transistor to a small speaker, via the 100k<br>
resistor? Or without it?<br>
I wouldn't expect a sound in either case, due to the tiny tiny signal<br>
(if the 100k is included) or the heavy heavy loading of the transistor<br>
(if it's not).<br>
<br>
Btw, when changing the 2.5 V points into ground, du you have a CV<br>
generator that reaches 2.5 V below ground as it needs to do?<br>
