Proposed as a Blocker for 28-final by Fedora user lbrabec using the blocker tracking app because:

 It was reproduced by several people that pulseaudio crashes when headphones are plugged into laptop. 

The closest violated criterion is for Beta - Working sound (The installed system must be able to play back sound with gstreamer-based applications), which doesn't exactly cover this problem, thus proposing as final blocker.

May have to pick your poison here, the patch that likely introduces this is a fix for upstream,
https://bugs.freedesktop.org/show_bug.cgi?id=100488

"alsa: fix infinite loop with Intel HDMI LPE"

that said, I think reverting it for now is probably the way to go.

pulseaudio-11.1-16.fc28 fixed the issue for me

*** Bug 1554394 has been marked as a duplicate of this bug. ***

Discussed at 2018-03-19 Fedora 28 blocker review meeting: https://meetbot-raw.fedoraproject.org/fedora-blocker-review/2018-03-19/f28-blocker-review.2018-03-19-16.02.html . Accepted as a Final blocker: we consider this a sufficient conditional violation of Beta criterion "The installed system must be able to play back sound with gstreamer-based applications", the condition being "just try doing it with headphones, buster", to constitute a Final blocker. We also grant it a freeze exception for Beta, as this can obviously affect live environments, and use immediately after install from a live image, both of which can't be fixed with updates.

pulseaudio-11.1-16.fc28 has been pushed to the Fedora 28 stable repository. If problems still persist, please make note of it in this bug report.
