We have an ASUS E406MA laptop equipped with Intel N5000 CPU. After system suspend & resume, the audio playback does not work anymore. The device for sound output is listed as a headphone device. Plugging in headphones no sound is audible neither.
Here are the error messages after resume:

After bisect, we found reverting the commit b5a236c175b0 "ALSA: hda - Enforces runtime_resume after S3 and S4 for each codec" can solve this issue on Linux stable 5.0.x series.
This reverts commit a57af6d07512716b78f1a32d9426bcdf6aafc50c.

I thought this revert isn't needed if the i915 GLK fix is applied?
If the i915 GLK fix is applied, then this revert is not needed.
I have also sent the "i915 GLK" to stable mail list for Linux stable 5.1.x. But I am still wondering for 5.0.x, due to the commit dependency. Any idea for Linux stable 5.0.x will be appreciated.
It'd need a slight modification of the commit, but it should be fairly easy.
thanks,

You must hit the very same problem even after reverting this when the machine goes to suspend while playing a stream. So the revert is no proper fix at all.
