Another thing I have to point out is that when I uninstalled Cirrus Logic Amplifiers from Windows the same thing happened as well.

I don't see 2 I2Cs controllers for the amplifier or things like that while at it.
The amplifier is connected to Intel(R) Serial IO I2C Host Controller - 43EA (\_SB.PC00.I2C2) on Windows. The other 43E9 (\_SB.PC00.I2C1) controller is for HID. Nothing is connected to 43E8(\_SB.PC00.I2C0) for me.
