[solved] Answering my own issue. EAPDFix works now. The problem is that when I was installing Mavericks, boot kept stalling at [PCI Configuration begin] and I couldn't see anything. npci=0x2000, npci=0x3000 were not working. The only thing that got me past that was to remove Name (_ADR, zero) from Device (PCI0) Device (PCI0) { Name (_HID, EisaId ("PNP0A08")) Name (_CID, EisaId ("PNP0A03")) Name (_ADR, Zero) <<------------- had to remove this to get past [PCI Configuration begin] Method (^BN00, 0, NotSerialized) { Return (Zero) } Method (_BBN, 0, NotSerialized) { Return (BN00 ()) } Name (_UID, Zero) Method (_PRT, 0, NotSerialized) { If (PICM) { Return (AR00 ()) } I simply had to put Name (_ADR, zero) back. Now EAPDFix is working correctly: 0/23/14 8:10:08.000 AM kernel[0]: EAPDFix v2.0 Final Copyright (c) EMlyDinEsH (OSXLatitude) 2013-2014. 10/23/14 8:10:08.000 AM kernel[0]: EAPDFix: Fix type 1 enabled, will send the verb once to enable EAPD/Jack Sense at boot and after sleep. 10/23/14 8:10:08.000 AM kernel[0]: EAPDFix: Speakers has EAPD, Headphones has EAPD, Jack sense Fix Disabled. 10/23/14 8:10:10.000 AM kernel[0]: EAPDFix: Timeout on response read. 10/23/14 8:10:10.000 AM kernel[0]: EAPDFix: Speakers EAPD is down, Trying to power up... 10/23/14 8:10:10.000 AM kernel[0]: EAPDFix: Codec verb sent successfully to power up EAPD. Many thanks! Excellent work EMlyDinEsH!

*** Edit *** : Issue solved in my next post. All is good now. This is a terrific project, especially for the ALC269 that has an EAPD chip. Thanks for helping so many of us. I'm on Mavericks 10.9.5 with stock patched AppleHDA v2.5.3. Unfortunately, EAPD fix v2 and 1.7.1 are not working for me. I keep getting: EAPDFix: Failed to find Audio device HDEF@1B EAPDFix: Failed to find Audio device HDEF@1B EAPDFix: Failed to find Audio device HDEF@1B I don't know where else to look. That seems correct.
