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.
Good to hear.
But, there is already a quirk entry for this ID, so you'll need to put a chain there instead, I suppose.
Adding Hui Wang who added old fixup fir the mics.
Oh, I see. It might be that the "ThinkCentre Station" is actually refers to "ThinkStation P340" in that case I wonder if the plock/pop can be observed by Hui Wang as well and confirm that it is the same model.
do you have any suggestion on naming the chain for the P340 headset-mic and no-plop on lineout fixup enum/text/entry?
