IRQ Fix mean "system_IRQ.txt" in the patches ? (if yes, i applied it)

No. I meant what I wrote. If you're using MaciASL according to the README, you'll see "IRQ Fix" on the left.

how did you determine that layout id should be "3" because when i check info.plist it show 42 layout IDs?

Your question is answered in the ACPI patching guide.

Rehabman,
Long time since I contacted you. I am still working on the Lenovo Twist. I had everything going but only had issues with the battery indication and audio. I have fixed the battery indication but I still have issues with audio.

I am running 10.10.5. I am using clover with a patched dsdt. I have an ALC269vc kext with a layout ID of 1. I have done the audio layout change and the IRQ fix to dsdt.


The audio shows up now in "about my Mac", which it did not previously but I still don't have sound. This must be something simple but Iam missing it. About this mac shows Intel high def audio with an internal mic, speakers, external headphone and HDMI display port output.

Sound in system preferences still shows no output and input devices found.

Any ideas ? Thanks.
Srini

Download patchmatic: https://bitbucket.org/RehabMan/os-x-maciasl-patchmatic/downloads/RehabMan-patchmatic-2015-0107.zip
Extract the 'patchmatic' binary from the ZIP. Copy it to /usr/bin, such that you have the binary at /usr/bin/patchmatic.

In terminal,

if [ -d ~/Downloads/RehabMan ]; then rm -R ~/Downloads/RehabMan; fi
mkdir ~/Downloads/RehabMan
cd ~/Downloads/RehabMan
patchmatic -extract

Note: It is easier if you use copy/paste instead of typing the commands manually.

Post contents of Downloads/RehabMan directory (as ZIP).

Rehabman,

I am sending you two kexts.

1. The second one (1.18MB) is the one I used first and has layout ID of 1. This showed up in About Mac but no sound.
2. The first one (1.41MB) is now in the machine. This is supposed to be a universal kext handling all flavors of ALC269. It uses layout IDs from 1 to 7. I am using it with ID=1 but I do not know if one chooses among the flavors with the layout ID. I have not tried IDs other than 1. Again everything visible in About Mac but no sound.

A question here . When I need to change the layout ID in dsdt, can I repatch a patched DSDT or do I have to start with a fresh DSDT? I wanted to try other layout IDs to see if one of them will work.

Thanks,
Srini

Keep in mind that most ALC269 codecs need CodecCommander: https://github.com/RehabMan/EAPD-Codec-Commander (you should try with/without though).

You can change the layout-id by reapplying "Audio Layout 12", but changing the ID as required.

Rehabman,

I have tried all the layout IDs from 1 through 7 (w/o codec commander) without any luck. I have tried 7 and 1 with codec commander and no luck. Will try the other layout IDs also.

Did you find anything from the IOREG that I sent you?

By the way, the same kexts that go into S/L/E with chameleon/chimera can be used with clover, right?

Thanks,
Srini

Kexts should be installed to sle regardless of bootloader.

Rehabman,

This may be the problem.

1. I installed the battery kext into the clover Kexts folder. The battery problem is solved.
2. I did the same with the apple hda kext. The sound does not work.

I can put the Applehda kext into sle. This would mean that when I upgrade the OS, I would have to reinstall Kexts every time. Correct?

I was under the impression that using clover allowed one to upgrade the OS using the Apple updates and nothing else needed to be done. I guess this is not true.

Will repeat the process with installing into s/l/e
Thanks,
Srini
