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:


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.
