Title:
[regression][snd_hda_codec_realtek] repeating crackling
** Description changed:
- I'm experiencing a repeating crackling noise after 19.04 upgrade that
- start just after the boot and before the login.
+ [Impact]
+ After CONFIG_SND_HDA_POWER_SAVE_DEFAULT is changed to 1, the codec runtime PM
is
+ enabled, on some codecs or for some hw design, there
FWIW, I think a better way to do this is to ask Realtek to implement
correct de-pop function for this platform.
Of course blacklisting is still a proper compromise.

@Hui: I've installed the package as per comment #19 (sorry for the typo at #20)
and this has fixed the problem.
I've skipped the instructions at #12. Do you need additional tests?

Ok, I guess I got the wrong id. Can you also add the ids from the duped
bug so that can be tested too?

@Hui does the test driver in comment #13 add 1002:437b to
power_save_blacklist? From the duped bug seems we also want to add
8086:a170 to the blacklist as well, or else change
CONFIG_SND_HDA_POWER_SAVE_DEFAULT back to 0.

please install this dkms on rc4 or v5.0 kernel, reboot and test.
If you add the workaround of #12, please remove it first.
thx.
** Attachment added: "oem-audio-hda-daily-dkms_0.1_all_blacklist_pm.deb"
It is an issue of power_save setting. It is not a driver's code issue,
it is a kconfig issue. From rc4, the CONFIG_SND_HDA_POWER_SAVE_DEFAULT
is set to 1 rather 0, then the codec enables the runtime PM, that
introduce the noise.
You can workaround it by adding an module parameter (/etc/modprobe.d
