Ditch that "pre-programmed" microSD card, get a new one, about 16G to 32G, Class 10 or A1, and flash the latest raspbian stretch with desktop using Etcher.
once installation is all complete, then install the drivers for the sound card (I take it you're using a Pi-Top speaker module). Battery monitor is already included in the latest raspbian image, you just have to enable it at the panel.
if you are not using the Pi-Top speaker module and using the audio jack to output audio to a set of USB speakers, then just connect the speaker plug to to the audio jack. Make sure you select "Analog" as the audio output device.
I have a Pi-Top v1 with a battery in "coma" state, but that didnt deter me from still using the Pi-Top as always plugged in RPi-LapTop.
( RPi model used in Pi-Top is Raspberry Pi 3 Model B, in USB native boot)
