I'm curious, why does Chirp advise you on Baofengs "(volume may need to be set at 100%)"?

In 4+ years I have been programming these radios I have only turned the volume up enough to get them powered on. These radios are programmed digitally using serial communications. The programming cables that I have don't even have wires for the speaker audio or mic audio. The volume level should not make any difference.
That being said, someone insisted that it clearly made a repeatable difference for them. Volume low = unreliable cloning. Volume high = reliable cloning. Maybe something in the volume settings of these cheap radios affects the TTL levels of the serial communications. Setting the volume to high shouldn't hurt anything (the internal speaker is disconnected) so I reluctantly added "(volume may need to be set at 100%)".
