That's an old meme. Audio "just works" for years. With pipewire, it's actually better than MacOs and Windows in many scenarios. (yes, yes, there's always some one-off issue, but that's not Linux-specific - I've got some "audio broken on windows" stories to trade too, and can tell you about macbooks going right-channel-only mono when using specific BT codecs)
I don’t think it’s that big of an issue, but having come back to linux via the steam deck this year I laughed that literally the first bug I encountered was an audio one. This one: https://github.com/ValveSoftware/SteamOS/issues/822
