Power-saving is causing loud plops on the Lenovo C50 All in one, add it to the blacklist.

Before adding to blacklist, could you try some usual suspects? For Lenovo, you can try at first to pass model=,tpt440 to snd-hda-intel module.
(the first comma is no typo but to pass the model name to the second controller for Realtek.)
The above will add some bogus dock jacks, so it's no solution but to just to test whether it avoids the clicking noise.
Sure, note I'm just forwarding these bugs from Fedora reporters, more often then not I don't have access to the hardware myself.
I always add a BugLink tag to the bug, so perhaps next time you can reach out to the reporter directly ? I've forwarded your request this time.
I also always ask for alsa-info.sh output, so following the BugLink will also give you access to that.
So the user just replied:
"Still hear loud pops with 4.16.7-300.fc28.x86_64 using snd_hda_intel.model=,tpt440 (confirmed enabled in sysfs).
I think in some sense this is just 'poppy' hardware -- it's always emitted a pop (though not as loud as these) when the sound card is initialised, even under Windows."
