The script is at

Also, we need to know whether this is a problem with speakers that you
want to work around (which likely won't work), or a purely software
problem. As you are a Certified Electronics Technician, I assume that
you have a digital multimeter and a cable with a 3.5mm jack at one end
and just three wires on the other.

I want you to run this command:

speaker-test -c1 -t sine

and measure the output voltage of the card at its maximum volume in
three situations: with only an unloaded 3.5mm jack connected, with
typical 32-ohm headphones connected, and with your speakers connected.
