Thanks for your very thorough answer. 👍😀
I haven’t had any of those issues myself, I also use AMD and have for many years, everything always worked fine with the default setup.
Some years back I too changed Pulse audio settings, not because the defaults were bad, as I remember it, it was pretty much Pulse audio default settings they used.
But in early days there could be problems with Wine that required higher priority for Pulse audio, and some fine tuning of buffer settings that may be hardware specific.

There is however one thing that annoys me with Manjaro, and that is that updates sometimes overwrite config settings I have manually made changes to. Arch generally didn’t do that as I recall, but made a notice about the config file from the update being copied with a different name to preserve manual settings, which is excellent.

I’ll check out what they write about discontinuing Antergos. But for now it’s kind of a “if it works don’t fix it” situation for me.
