This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Fix] Avoid using pm_runtime_force_{suspend,resume} helpers to ensure codec suspend/resume flow, and also ensure HDA driver and PCI set correct wakeup settings. [Test case] Plug headset, unplug headset, switch audio ouput from speakers to HDMI to let Intel HDA auto suspend. Suspend/resume the system, plug the headset again, hear no sound. With the patch series applied, the issue is gone. [Where problems could occur] If there is bad firmware/hardware that makes codec have system-wide wakeup capability, direct-complete flow may trigger unwanted system wakeup or even break system suspend. The series was tested on both AMD and Intel platforms, with Realtek and Connexant codecs respectively.
