Bug description:
[SRU Justification]
[Impact]
HD-audio codec shutdown is not quite right when powering off the
controller side. This causes pop noises on some platforms.
[Fix]
While previously in bug 1939541, a local fix for Cirrus CS8409 only is
proposed the upstream as in
https://lore.kernel.org/lkml/20210812183433.6330-2-vita...@opensource.cirrus.com/
. This initiated a discuss to create a generic solution as in
https://lore.kernel.org/all/20210813081230.4268-1-ti...@suse.de/ .
[Test Case]
Shutdown Ubuntu that is running a patched kernel and see if a pop sound
is still made.
[Where problems could occur]
While this tries to suspend the codec devices at shutting down, out of
tree drivers without (runtime-)suspend support may fail to react
correctly. And since this removes .reboot_notify callback from struct
hda_codec_ops, it may break such oot drivers, too.
[Other Info]
This depends on patches for https://bugs.launchpad.net/bugs/1939541 .
========== original bug report ==========
[Reproduce Steps]
1. Attach external speaker to SUT
2. Try to reboot SUT or stay in OS.
[Results]
Expected Result
No noise.
Actual Result
Noise will pop up during WB or stay in Ubuntu OS when external speaker
attached.
[Others]
[Scenario 1] Login to the Ubuntu OS.
(Occurs only in Cirrus, within 5 seconds after logging in to OS)
Can 100% reproduce on Cirrus MB with Ubuntu. Noise can be heard (咚咚 Sounds)
after login the Ubuntu within 5 secs.
[Scenario 2] Reboot Ubuntu OS
(Both Curris and Realtek happen. WB/CB/shutdown OS)
Can 100% reproduce on Cirrus MB with Ubuntu. Noise can be heard While both
exiting OS and entering OS.
