Hi All,
For Fedora 28 we plan to ship the kernel with snd_hda_intel.power_save defaulting to 1:

We've had an update for F27 in updates-testing for a while which made the same change for F27, but we've received several bug reports about plops / click sounds on start / stop of playing audio:
https://bugzilla.redhat.com/show_bug.cgi?id=1525104
I know others have probably already tried fixing this, but I'm wondering if there are any ideas how to fix this / things to try?
Ideas of my own:
1) Mute the speakers / headphone output in the mixer before activating power-saving. Question how hard would it be to make this happen?
2) Put a delay between various steps involved in turning things off / on.
Regards,
Hans
