“mormegil, Thanks so much for taking so much time to help me. I'm still not sure what I was doing wrong with the codec patching, but my solution turned out to be voodooHDA 0.2.2 64bit, installed in /System/Library/Extensions, and rebuilding …”

“Do you have voodoohda installed all this time? When you're using patched applehda? same goes to gurru Mormegil, No, I don't. I just have tried voodoohda, in the past, in the effort to get it to make a dump.”

“Mormegil, Does the fact that voodoohelper can't dump, for me either, mean anything? I'm not quite sure where else to go from here.”

“Guru, What version of codecgraph are you using? When I try it, it works fine:”

“mormegil, Thanks, but no luck that way, either: 9/6/09 3:09:51 PM kernel Sound assertion "0 == pathMap_aDriverInstance" failed in "/SourceCache/AppleHDA/AppleHDA-174.1.1/AppleHDA/AppleHDADriver.cpp" at line 1459 goto Exit 9/6/09 3:09:51 PM …”

“Is the codec dump made by yourself or did you download it? You're on a lappy too yeah? Yep, this is a laptop...a 17" desktop replacement. I made the codec dump myself, using a Ubuntu 9.04 x64 livecd, following TheKing's instructions.”

“mormegil, No, my sound isn't working. I have no input and no output devices listed in the Audio part of System Preferences. I also get those assertion failures that I pasted in, above, when a sound tries to play. Thanks so much for continui…”

“Mormegil, AAH...I see what you mean about the misplaced Info.plist file in AppleHDAPlatform. I must have typoed a replacement, at some point. Anyway, I replaced those Info.plist files with the ones that you sent, and rebooted. I still get t…”

“Mormegil, Thanks for taking so much time to help me. I went back, and fixed the locations of the Info.plist files, and re-hexedited the AppleHDA file. I now get the AppleHDA.kext to load, but I get the following exceptions in my system.log:…”

“OK, I made all the changes, mormegil, to AppleHDA.kext, including replacing 8508ec10 with 8308ec10. However, I still have no sound. I noticed something interesting in my system.log, though: 9/6/09 11:11:55 AM com.apple.kextd[10] Can't load …”

“mormegil, Ahhh...thanks for filling me in, about the codec. Is there nothing else that needs doing, to patch the codec, other than changing the identifier from 10ec0885 to 10ec0883? That seems very simple. I'll give that a shot, though, and…”

“Just like others here, I'm trying to fix a silent 10.6 machine. My machine is a Clevo M570RU-U, with an ICH8M, and a Realtek 883 codec. I've been through TheKing's procedure to create a patched AppleHDA.kext, adapted to Snow Leopard with th…”
