Hello,Mirone, my audio card is CX20751/2, speaker is working but both internal and external mic are not, can not detect the input level, could you take a look to see anything is wrong.And cx20751/2 is very similar to cx20753/4 which can use the int mic.View attachment AppleHDA-274.7-CX20751-2.zipView attachment codec.txt.zip
