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

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.

Regards,

Hans
