All,
    Have been programming multiple (15+/-) UV-5's, for our group, for 
several years. Never have had to mess with the volume. Versions of hardware 
at the beginning was the worst. Cables and drivers, were a pain for a while 
to, but not the radio controls.

The digital data is proviced on connections that have nothing to do
with the connections for the analog speaker audio or the analog
microphone audio. In addition to the audio wires (that aren't included
in the programming cable since they are not necessary to have for
programming) and the data wires, there is even a connection that
provides DC voltage (5V or 3.3V depending on the radio) to power
external devices.
