As confirmed above, the mic has the same root cause as bug 2164574 (GPIO
11). The upstream fix is commit 6da1f3437435 (andy/linux-gpio-intel),
see bug https://bugs.launchpad.net/ubuntu/+source/linux-
hwe-7.0/+bug/2164574 for the links. No ALC245 fixup is needed.

One more tip: once the mic works, keep the input volume at about 30-40%.
At 100%, PipeWire adds about +60 dB of gain (Capture +30 dB plus
Internal Mic Boost +30 dB), so the mic overloads and you only hear loud
noise. Also check that the source is not muted.
