Hi!

[ Upstream commit 9fc149c3bce7bdbb94948a8e6bd025e3b3538603 ]
The broken jack detection should be fixed by commit a6e7d0a4bdb0 ("ALSA: hda: fix jack detection with Realtek codecs when in D3"), let's try enabling runtime PM by default again.
I believe experiments should be done in mainline, not in stable.
Worse problem is that a6e7d0a4bdb0 is not in 4.19-stable, so this will likely break jack detection.
Best regards, Pavel
