I have great sound out of Fedora - I choose as my output device “Analog output - Built in Audio”. It sounds low tech compared to the ones you are describing but it sounds great on my Bose companion system.
I guess it would also depend on what output you’re using for sound out - I use the light green analog plug that comes out of the built-in sound card on my ASUS mobo - it’s an analog pin labeled “front”. So it depends too on your sound card capabilties and what output plug you choose. All I know is that mine sounds awesome.
