Inductance and capacitance need to be taken into account for cable lengths more than a small fraction of a wavelength. But the wavelength in free space for 20 kHz (usually accepted as about the highest frequency that human ears can hear) is 15 km (if I've done that right in my head). In a cable the plastic insulation has a higher dielectric constant than empty space, so the wavelength in the cable would be something like 10 km. If your cable length is of the order of 10 m you can forget the inductance and capacitance.
