Already sent to alsa-user, however a developer asked to send this also on devel, so here it is:

I have audio stutters with an ALC892 Realtek Chipset on a B450 GAMING ELITE board from Gigabyte during acquisition (at least with microphone input, both front and back. Line in not tested). No issues with Windows.

After opening an issue and testing with a PulseAudio developer, he has determined that the issue is not within PulseAudio, but on ALSA.

There are already two issues about that on the bug tracker on Linux, namely this two:

ALC892: https://bugzilla.kernel.org/show_bug.cgi?id=203351 ALC1220: https://bugzilla.kernel.org/show_bug.cgi?id=195303

To me both appears to be identical, for this reason even if I have a ALC892 I’ve posted on the second one, just because it had more posts.

The particular thing is that acquiring with PulseAudio on Audacity show the problem, however using ALSA directly the issue is not present. Trying using arecord still present the issue from PulseAudio.

Tried to play with the parameters /sys/devices/audio to no avail. Compared the pinconfigs from Windows, they are identical.

Can someone try to help me fix the issue?
