This also did not work for me (Dell E6500, IDT audio byteflipped hex:8508EC10) even with pathed DSDT. However now I have a new mysterious New Interface Detected - PCI Serial Adapter (3) in my Network Prefs...

Following your guide mormegil, now with all the info you helped me gather, I have "found" that ALL the "assertion "0"" verbose errors are gone, all except one! The system does not crash anymore or KP's, once in a while it triggers double verbose messages. An error I know I created, because I deleted an entry to make my plist as close in structure as your guide, and I'm pretty sure it had this name. I inside it was an entry called codecAddressMaskData. The whole verbose line reads
Code:
Sound assertion "0 == codecAddressMaskData" failed in "/sourceCache/AppleHDA/AppleHDA-174.1.1/AppleHDAcontroller.cpp" at line 1159 goto ExitYou know where I can find this info regarding my chip? |

Yes, but with voodooHDA.
I just went through it again, and I surely did something wrong the last time because I didnt find that codecAddress thing on the way. Started again and made double sure I had vanilla appleHDA. I have my very own codec dumps from linux, the only guessing I did was pathmapID being 9. The rest is absolutely my system. Rebooted and KP'd unfortunately. Note: When I redid the steps, I noticed that when editing AppleHDA/macos/appleHDA hex to byte flip the codec, when you save, it created a text file (appleHDA.txt) and the hex is renamed "appleHDA~". So the second time I copied it out to another folder, edited, saved, created the same output, renamed and removed the "~" and copied it back in (just hex file). Dont know if this is relevant, but I thought it would be interesting to share. |
Youre using hexedit right? it shdn't create a txt file.
Anyway, as I said before, I assumed a working kext for this to work. Run leopard and try out all the ready made kexts you can find until you find one which works. Try searching insanelymac forums. You're just looking for a set of plists with the right configdata, layout and pathmap for your codec. Once, youve done that then you can start thinking about porting it over to SL |
yes, I did. From the link provided. I replaced all 4 entries, File-> Save.
Maybe because I have Finder "showing all hidden files" ? But it did also alter the unix file adding "~" at the end. Will do, hadnīt thought of that !! thanks!! :) |
Hi again
