No IOReg?  Request the latest download; 10.9.3 has been available for download since the release.


Here, have another IOReg, because I never get tired of redumping and uploading those. Also redownloading all 5.32GB of the Install OS X Mavericks.app, because the one I downloaded last week still had a 2.6.0f1 kext inside, unless I need to actually install it, or at least prepare boot media using myHack, to get at the 10.9.3 version of the AppleHDA.kext bundle.

Right, I changed the InjectKexts option from its default of Detect to Yes, and I will reboot in a moment. For now, here's the output of information on my AppleHDA.kext.


du -h AppleHDA.kext > AppleHDA_du.txt


find AppleHDA.kext -type f -exec ls -l {} \; > AppleHDA_ls.txt


Do note that this is version 2.6.0f1, because Apple hasn't yet updated their Install OS X Mavericks.app past 10.9.2, and I would have to reinstall that and update to 10.9.3 again to get the "proper" 2.6.1 extension.

What do you mean, not a native AppleHDA.kext? I packed it up directly from the installer.


open /Applications/Install\ OS\ X\ Mavericks.app/Contents/SharedSupport/InstallESD.dmg

open /Volumes/OS\ X\ Install\ ESD/BaseSystem.dmg

cd /Volumes/OS\ X\ Base\ System/System/Library/Extensions

ditto -ck --keepParent --sequesterRsrc --zlibCompressionLevel 9 AppleHDA.kext ~/Documents/AppleHDA.kext.zip


And that's precisely what I uploaded in my last post. The patched kext is what I currently have in /S/L/E after running the ~/Downloads/audio_ALC898-master/cloverALC/audio_cloverALC898-90_patch.command from Finder, which merely inserted the modified layout files from 898.zip renamed to .zml.zlib.


I'll attach screen shots and an IOReg from the current state of the system. If you want IOReg and screen shots from when I rebooted without any injection, and with just the native kext, I already attached those to a previous post.


Current IOReg dump exported as Umaro.ioreg, packed to attached Umaro.ioreg.zip.


Screen shot of System Information -> Hardware -> Audio -> Intel High Definition Audio attached.


Bonus screen shot of Audio MIDI Setup thrown in, highlighting the one Line Input that registers, also attached.

There is no such thing as 10.9.2 state Clover patches, one Clover patch works on all 10.9 versions.  Without files attached, no idea what you have done or why it is not working.  By mixing procedures, the probability of success is very low.  Suggest starting over with a complete, native AppleHDA.kext with one procedure or the other.  Reply with the resulting files.


I wrongly made the assumption that the layout files changed from 10.9.2 to 10.9.3. I also wrongly assumed that the realtekALC.kext changed as well, so I had checked out the version of 898.zip from the 10.9.2 release commit in the repository.


With the latest master, patching the native AppleHDA.kext (attached) with the CloverALC script (result attached as well, as "patched" file), and applying the xml>zml and 898 patches in Clover, I get sound, but the input now shows only one line input, presumably connected to the rear line input jack.

At least now, the DevShortName mess is gone, so that's a good thing.

I extracted AppleHDA.kext from a freshly retrieved Install OS X Mavericks.app, which turned out to be 10.9.2, and extension version 2.6.0f1. Even after resetting all of the Clover patches to the 10.9.2 state, I was not able to make that produce sound at all.


I was able to install the pre-patched 10.9.3 extension without any Clover patches or realtekALC.kext, with Clover simply acting as the layout 1 enabler. That produces sound, but the recording doesn't quite work right. The front jack registers in inputs as Internal Microphone, until I plug my headset into it, then it registers as Line Input. It manages to produce a working recorded signal for about 30 seconds from switching the input to it, then it goes silent until the inputs are switched again.
