Having the same issue on the MSI X370 Gaming Pro Carbon, audio is fine but the microphone is having weird behavior that differs depending on configuration.
When audacity is launched it will trigger the bug that increases the recording speed to be insanely high pitched and fast. Prior to using audacity i will hear a robotic noise while speaking that is also present as a robotic echo.
Making use of the tsched=0 the robotic distortion is gone but replaced with severe crackling that over time becomes less severe but still very notable.
Very notable here is the buffer size which falls short of the required buffer size 44800 while in Windows the card can go up to 24-bit , 192000 without having to resort to a third party driver.
