In the analog signal world volume control means throttling back the voltage level of the audio signal prior to reaching your amplifier. That’s how volume is controlled; by reducing the signal voltage using a voltage divider.

A higher voltage audio signal will be louder relative to a lower voltage signal. On the other hand, when you attenuate an audio signal you reduce its average voltage level. Thus, volume control is simply the reduction in the effective voltage of an audio signal, i.e. attenuation.

The louder you turn it up, the better it’ll sound because there’s less to get in the way. Digital volume controls are the same in this regard, but a whole other story. They add nothing to the signal path: instead they rearrange the digital numbers to achieve a lower volume.

One of these two connections (A) is attached to the audio source and the other side (B) is connected to ground (zero audio). A third contact (W) is pressed against this strip and connected to a knob or a lever so that the user can move the contact up and down the length of the resistive strip. This contact becomes the output of the volume control.
