dgsga Posted November 15, 2008 Share Posted November 15, 2008 Hi all Thought I'd share a discovery that means you no longer need HDAEnabler.kext to load AppleHDA, only EFI strings. If you have an award bios you can do the following (all audio info shows up in System Profiler): Create a folder in windows containing your bios file and cbrom.exe. Use cbrom.exe (run in command pronpt in Windows) to extract the ACPI table from your bios using the command: cbrom yourbios.bin /acpitbl extract. It will prompt you for a filename, just press enter, and it will save the table as acpitbl.bin. Use a hex editor such as HexEdit to search and replace the asci string AZAL with HDEF. In my bios there were 2 instances of this. Remove the old acpi table from your bios using the command: cbrom yourbios.bin /release. Replace with the fixed table using the command: cbrom yourbios.bin /acpitbl acpitbl.bin Reflash your bios and remove HDAEnabler.kext once back in OSX. Install the efi string for HDEF using EFIStudio. Reboot and enjoy! I'm sure you could do the same for other bioses if you have the right program to extract the ACPI table. For good measure I've also attached my 10.5.5 ALC888 Desktop kext with: Front headphone jack - working Rear line out jack (green) - working Rear line out jack (black) - working Digital in/out - working Rear line in jack - working No sound assertion errors on boot The only darn thing I cant get to work is the front mic jack. It shows up in Sys Prefs but no joy when a mike is plugged in... Cheers, and thanks to TheKing, MadTux and Taruga who got me going with this.

mackerintel Posted November 15, 2008 Share Posted November 15, 2008 I replaced HDAC to HDEF since a while (using my DSDT override http://forum.insanelymac.com/index.php?showtopic=132757) and replaced ALCInject by EFI string. But I didn't try replacing AppleHDA by vanilla one. Will try and report results. (but still I have more problematic ALC662 codec) Update: Still need patched AppleHDA to get my audio to work Link to comment https://www.insanelymac.com/forum/topic/136531-one-step-closer-to-vanilla-sound/#findComment-966790 Share on other sites More sharing options...

mackerintel Posted November 15, 2008 Share Posted November 15, 2008 do u know what program should work with phoenix bios? and... where do I find my bios file? Try my DSDT override. Same result, less risk. And should work with any BIOS Link to comment https://www.insanelymac.com/forum/topic/136531-one-step-closer-to-vanilla-sound/#findComment-966879 Share on other sites More sharing options...
lensboard Posted November 15, 2008 Share Posted November 15, 2008 My rear mic jack works, but not the front one either, so don't feel alone in this. I have the ALC888 sound also. By the way, you should be using a USB mic anyway, analog mics introduce to much noise into the sound. You get much better results with a USB mic.

Winther Posted November 28, 2008 Share Posted November 28, 2008 Hi Are you getting the 5.1 digital output to work with full surround? (Is the soundcard showing up in the Sound/Midi multi speaker setup). /Mattias Link to comment https://www.insanelymac.com/forum/topic/136531-one-step-closer-to-vanilla-sound/#findComment-980645 Share on other sites More sharing options...
