Full volume white noise when fluidsynth init without soundfont

[muaiyadh]

Some context: I'm using Pop os and I am somewhat new to Linux. I've been having some issues with sound (volume, when headphones plugged in, is correct, without them is always full volume), but I'm not sure if this is the main cause, as I was using my headphones.

By opening python in the terminal and running:

from mingus.midi import fluidsynth
fluidsynth.init()

I got a loud white noise that blew my ears away.

I'm not sure if that's what caused that loud noise, as I was trying a few commands before that as well:
fluidsynth.init('sf2')
Though when that didn't work, I hit CTRL+C to cancel it.
After some trial and error, it seems the issue only sometimes happens if I cancel using CTRL+C or such.
