Puppy doesn't even come into the equation. If your monitor has built-in speakers (not many do), you just plug your FireStick into the monitor's HDMI port, fire up the monitor and the FireStick, and you're off. If not, you may need to purchase additional items to add the "missing" audio back again.
This has absolutely nothing to do with software at all (the only software needed is already running on the FireStick, as it's basically an embedded lightweight OS to start with). This is ALL about the hardware.
