I have a question regarding the installation of the Audio EFI string.

What I have now done doesn't seem to work. Here's what I did: I've downloaded the .ZIP file supplied and installed the kext files using kext helper, after that I used the EFI string also supplied by Gold. I've tried using EFI studio, but it didn't seem to have an option for audio, so instead I selected a random video card, removed the EFI string supplied by the program, and replaced it with the one supplied for the audio support.

Am I doing something wrong? My X61 seems to have working audio option, but there's no actual sound coming out of the speakers/line-out.

Any help appreciated.

Further information regarding installation and version:
Thinkpad X61 7675-CTO
Snow Leopard 10.6.3 Vanilla installation w/ myHack updated to Vanilla 10.6.4 with out any modifications.

Working from the get go:
Graphics
Wireless
Bluetooth
USB

Installed kexts:
PS2 kext
SleepEnabeler kext
AHCI kext
Intel internet kext
SDHC kext

Anything else I should install? I have the feeling that my screen is also at a very low brightness, and I can't seem to find any option to increase/reduce it. Is this a known issue with the x61's?

Is there any need for me to "upgrade" for an example my graphic drivers? I know for an example that it is normal in Windows to always download the latest release of drivers from the manufacturer, because the stock Windows drivers just don't cut it. Any input on this, please?

I would be glad with any help, really. As you can see I'm still a newbie when it comes down to kext/efi string editing, or any rather none vanilla OSX86 editing.

Thus I thank you for this very useful thread, which was a lot of help for me just on his own.

Can everyone in this thread get sleep functionary and when resume from sleep, get all devices work correctly?
My x61 can sleep and wake, but when wake from sleep, thinkpad's broadcom bluetooth chip goes not detected.

My osx86 installation method is this thread's vanpire13's one.
CPU management and ACPI functions works with SL native via DSDT mod.

Does anyone have any solutions for Bluetooth work after resuming?

I just finished getting the pathmaps figured out and now have working internal and external mics. I still don't have any volume control on the internal mic though. Here's my AppleHDA.kext file. I'm trying to see if I can get autosensing working for the mic and get rid of the error messages at boot.

I have also attached my DSDT file, which removes the need for the EFI string by putting everything (including device descriptions) into the DSDT file. I have also renamed several devices to match the MacBook device names.

BANKERROR: This DSDT file solves the bluetooth problem. As for your trackpad, you may need to get a copy of the ApplePS2.kext that has the trackpad plugin inside. My X61 has no trackpad, so I removed that plugin. As for a clean install, I just do a default install with aitkos with the sound kexts unselected and ApplePS2.kext selected (this will have the trackpad plugin you need). Once it's installed, I remove all the plugins from Extra/Extensions and copy in mine and install my DSDT file. I use Kext Helper to set my permissions correctly.

vampyrex13, Thanks for your great work!
I'll try your new dsdt and kexts, later.

BTW, My x61 doesn't have trackpad. I was mistaken. That was trackpoint, sorry.

Now, My trackpoint have worked course I put AppleACPIPS2Nub.kext and ApplePS2Controller.kext from /E/E to /S/L/E .
But I don't know why.

vampyrex31, Do you know the reason?

vampyrex13. wow! That's great working.

working sound & mic, bluetooth perfectly~~ even more sleep/wake up

Thank you.

But. i have a problem yet. FN+F4 is not work to sleep.

Good Good

I tried vampirex13's new dsdt and kexts.
bluetooth goes fine. It work after resume. Great!

Yes, I have same problem HOT KEY's for sleep(Fn + F4) and brightness control(ScrLK and Pause).

vampirex13's DSDT work is awesome. I want to look dsdt.dsl file and composing method.

Done. Here is my current DSDT file, revision 35. My brightness works fine on my X61 as long as I don't have an external monitor attached. I don't recall if the Fn-F4 sleep combo ever worked, because I never used it since I just close the lid to put mine to sleep.

Woohoo, I finally got the AppleHDA.kext fully working with zero errors. God, I think I rebooted my laptop over 50 times trying to get it completely debugged. Everything works, but it's a little quirky if you try to switch to Line Out (UltraBase rear mic input) and External Mic (right mic input). I found that I sometimes lose the External Mic input when switching to the Line Out and vice-versa. I think it's because of how the Levovo reroutes the audio to the external Ultrabase dock. I had the same issue when using VoodooHDA.

I'm sorry, my x61's brightness control key worked when my x61 was undocked.

Thanks for your fixed files!
Many people who own x61 will welcome your works.

Wow, 50 reboots, god bless your laptop
