If codec is in runtime suspend, but controller is not, hotplug events are missed as the codec has no way to alert the controller. Problem does not occur if both controller and codec are active, or when both are suspended.
An easy way to reproduce is to play an audio stream on one codec (e.g. to HDMI/DP display codec), wait for other HDA codec to go to runtime suspend, and then plug in a headset to the suspended codec. The jack event is not reported correctly in this case. Another way to reproduce is to force controller to stay active with "snd_sof_pci.sof_pci_debug=0x1"

[1/1] ASoC: SOF: Intel: hda: fix hotplug when only codec is suspended commit: fd572393baf0350835e8d822db588f679dc7bcb8
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
