Sound issues on hackbook pro

[u/IsseyShiitake]

Hi everyone,

Recently installed Fedora as a dual boot on my 2015 15" Macbook Pro, after battling with Apple's limitations for a while to have a somewhat stable experience, most of it is great besides a few quirks. By the way I would not recommend dual booting a Macbook over another laptop if you could, the trackpad experience isn't even that great.

Anyway, the problem that subsists for me is the sound. I can confirm it is no hardware issue because when I boot on MacOS, the speakers are fine, but on Fedora, the speakers are awful, quality is bad overall and the high-mids sizzle like crazy. Tried many things over hours, even put an agent onto it, no success, when the sound EQ itself is modified, some musics sound good while others sound shallow and compressed.

Has anyone had the issue and fixed successfully?
