Help: To find out Internal Mic nodes #36

Closed plsh2me closed 2 years ago

plsh2me commented 2 years ago

Hi, Can you please help me to find the internal mic nodes. Speaker, Headphone and Ext. input seems OK, but no int. mic. I have attached the output and the codec dump, please suggest me the possible solutions. Thank you output.zip

There's no Pin Complex Node for an Internal Mic in this schematic.

7, 8, 9 are inputs, but only as Line-In.

8 - 35 - 25 = Mic via Jack, but not internal

You hav to try all the Nodes which can be IN and can be attached to either 7, 8 or 9

plsh2me commented 2 years ago

Yes, you are right. 8-35-25 =Mic via jack. Rather than this which could be the possible IN. Cause I don't see any IN nodes in the schematic.

Analyze the dumpdec.txt.

19, 18, 26 can also be IN.

Maybe it's one of these codecs which require additional data: https://github.com/acidanthera/AppleALC/wiki/Dumping-processing-coefficients
