Let's check other possibilities at first, e.g. setting auto_mute_via_amp flag. This can be achieved even via hints in an early patching specified via "patch" option of snd-hda-intel module (see Documentation/sound/hda/notes.rst for some information).
Unfortunately the auto_mute_via_amp has no effect on the pop. line_in_auto_switch and pin_amp_workaround have no effect either.
How about applying alc_fixup_no_shutup() or alc_fixup_disable_aamix()?
it looks like
SND_PCI_QUIRK(0x17aa, 0x1048, "Lenovo ThinkStation P340", ALC269_FIXUP_NO_SHUTUP),
in alc269_fixup_tbl[]
alone fixes the pop noise, I'll send a new patch to do this instead.
