So at 1/10 volume my laptop sounds about the same as on 10/10. At 10/10 The high frequencies might be a tiny bit more pronounced, but that’s it. There is only one audio output device.
What can I do to fix this issue?
Flat laptop? where the developers/engineers puts a great sound here? common sense. Is as TV… You need buy a great speakers… Or buy a external usb audio card (fairly good) + bluetooth speakers… 
Yes it is a flat and thin laptop. But my volume control does work on windows. So what you are saying doesn’t apply here.
Windows? Hey! We are using Fedora here… Well, 1, 2 3.…
David, I am not here because I want help with the audio on windows. The sound on Windows is fine, I was simply saying that the sound on fedora does not work they way it does on Windows.
I have a flat laptop and the sound is bad here in Fedora… as Windows… If you want test o improve (tune) the sound; you can touch pulse-audio. I dream yet with a equalizer or decent “pulse-audio” gui. Here the results with my bluetooth (Index 2).
