Again a correction: the current default setup for Raven corresponds to
position_fix=6 option. It's not a simple LPIB read but contains some
awkward correction that takes the FIFO size into account.

Yea, same here on B450/ALC892 with tsched enabled (which AFAIK the batch

Then I have no better idea for now than disabling the tsched on PA.
The patch below is a combination of the former patch (modified no.6) and
the flag set to enforce tsched=0. This should work without changing PA
config.
Let me know if this works better. If the things work reasonably enough,

Patch 2) on the 1022:1457 ALC1220 (X370 Pro Carbon motherboard).
Using the default settings i no longer hear the robotic echo issues in my
microphone recordings and i am able to get good recordings with Audacity.
Is this with tsched=0? I wonder why PA gets the position information so
often. Without tsched change, PA should access to the hardware much
less frequently.
In anyway, one another interesting experiment is to reduce the max
period size, something like below on top of the previous patch:
