Yes, I have the same errors on Console but haven't found a way to get rid of them. Also no one-click mute for me.

Why don't you try iPC? Brings you straight to 1.5.6 without the need to upgrade. Leave the AD1984 sound driver of it out though, as it will install the AzaliaTurbo1984 that you actually don't need.

You take the EFIStudio.app, select HDEF from device list and click "Add Device" button. New window opens with both XML and binary representation of the EFI string, you'll update the PCI ID-s and Layout ID in the XML part (binary is updated automatically) and when done, hit the "write to com.apple.Boot.plist" button. That's about it! You might want to save your conf in a separate file for backup. There are 2 buttons for this, but only the Save Hex really saves my new EFI string. YMMV. And yes, the internal speaker is muted, when you plug the headpones in.

Hello and welcome to everyone. This is my first post in this forum. It has been an immense source of knowledge for getting the iPC 10.5.6 up and working on my Lenovo ThinkPad T61 Widescreen. As for many, the AD1984 HD Audio Codec has been a real PITA to get working. Currently I am that far, that I have Internal speakers, Headphone-, SPDIF-out and Mic In working. What I have failed to get working is the internal mic. I am using the iPC 10.5.6 installation, EFI and AppleHDA.kext with modded plists inside. The breakthrough came after reading chapter 4 of Intel book titled "High Definition Audio for the Digital Home Proven Techniques for Getting It Right the First Time". Upon little searching you'll find an electronic copy in the web. That chapter copies most of the HDA spec document but in a more readable form. Also it was the only one to explain the importance and conventions of the pin configuration parameters "Default Association" and "Sequence". The pin config defaults from Vista are 100% from this book. And that is the problem under Leopard, as it does not seem to like pin configs where multiple pins share the same Def. Association number. Therefore I modded the pin config defaults in AppleHDAController.kext's Info.plist and created a Layout and Pathmap in AppleHDAPlatformDriver.kext's Info.plist Although the internal mic on T61 should be analog (not digital) and connected to port C (pin 0x15), the path setup (0x09 <- 0x0D <- 0x15) is 100% analogous to external mic, neither do I get level slider for it, nor comes any sound through. I'd be delighted to get more details about the physical setup of this mic on T61. To get the AD1984 ID correctly showed up in System Profiler and IO Registry, the EFI needs to be set up as follows: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>PciRoot(0x0)/Pci(0x1b,0x0)</key> <dict> <key>PinConfigurations</key> <string></string> <key>built-in</key> <string>0x00</string> <key>layout-id</key> <string>0x0000000a</string> <key>revision-id</key> <string>0x00000001</string> <key>subsystem-id</key> <string>0x00001984</string> <key>subsystem-vendor-id</key> <string>0x000011d4</string> <key>vendor-id</key> <string>0x00008086</string> </dict> </dict> </plist> Pay attention to rather bizarre and misleading use of keys "subsystem-id", "subsystem-vendor-id" and "vendor-id". And here's the AppleHDA, feel free to try it out! AppleHDA.kext.zip
