On playback start there is a huge plock/pop noise via the green jack used
in Line out mode.

The only way I was able to fix it to set the power_save to 0 for the
snd_hda_intel.

Hi Takashi,

Changes since RFC:
- Fixed up the PCI ID

ever since I have this workstation (three weeks) the plock/pop noise on playback
start bugged me. So far the only solution I have found is to disable the
power_save which I find acceptable on a desktop compared to the pops.

The alsa-info.sh output is can be found here:
http://alsa-project.org/db/?f=414b1b236fc73db386ad4f938bc3b304f6b30b05

Missing details from alsa-info output:
# lspci -nnk | grep -A2 Audio
00:1f.3 Audio device [0403]: Intel Corporation Comet Lake PCH cAVS [8086:06c8]
        DeviceName: Onboard - Sound
        Subsystem: Lenovo Device [17aa:1048]

CPU: i9-10900k

The machine have ALC623 codec and the jacks are correctly discovered and they
do what they supposed to be.
When I have the headset connected to the front and audio is routed there the
line out (green jack) from the back still prodices the plock/pop.

Is there a known quirk for similar issue or a better way to handle it?

Thanks you,
Peter Ujfalusi
