The internal mic boost on the T480 is too high. Fix this by applying the
ALC269_FIXUP_LIMIT_INT_MIC_BOOST fixup to the machine to limit the gain.

Applying this quirk itself is OK, but just wonder whether this model
has a docking station port. Recently we fixed the dock issue, and it
required to apply ALC298_FIXUP_TPT470_DOCK.

I assumed that on the T480 and similar models the audio on the dock is
connected through USB (the dock is USB-C + further pins), but I cannot
confirm this myself right now as I only have a T480 currently.
I have now contacted Peter Zhang of Lenovo about this and also to check
if other 80 series models may need the same fixup.

Hi Ben,
My understanding is same as yours. Recently Realtek Audio expert Kailang (on copy) submitted a patch for Dock as the attached, are you asking the same thing?
Looks like the issue is related to Dock model, there are many different Dock models, could you please let us know which specific dock model you mean? Thanks.
@Kailang, Do you have any suggestions or comments?
Thanks,

FYI, because of this unclearness, the patch from Benjamin is still
pending. I'm OK to apply it at first, then adjust later if the
docking station quirk is required, too. Just let me know.

Thank you Takashi.
I will also double confirm it with our Accessory BU guys about Ben's question when I back to my office. And will let you know if there was any different answer from them.

Hi Ben, Takashi,
The following comments from our Accessory BU hardware team FYI.
//
Most of dock audio is converted from USB if it is connected by cable, but CS13 Mechnical dock is not. We need to know the specific dock model first.
//
Thanks,

Thank you Takashi.
I will also double confirm it with our Accessory BU guys about Ben's question when I back to my office. And will let you know if there was any different answer from them.

FYI, because of this unclearness, the patch from Benjamin is still pending. I'm OK to apply it at first, then adjust later if the docking station quirk is required, too. Just let me know.

I think that basically answers the question and we can conclude that
the 80s series has USB audio on the docking stations.
CS13 is the previous generation docking (at the bottom of the laptops)
while the new models have a new docking connector at the side (which is
USB-C + 14 pins primarily for Ethernet incl. LEDs and likely some other
purpose).
Thanks,
Benjamin
