AppleALC — dynamic AppleHDA patching

calibre™ · March 28, 2016

may i suggest to lower down the support to Mountain Lion, since the zlib starts at 10.8.

I know its just easy, but nice to have it in the repo too.

hai vit9696 thanks for AppleALC.

Now works with Conexant CX20752. It's awesome and now i have untouched S/L/E

crusher · March 28, 2016

Well, there is no need in recompilation.

Just take "as.vit9696.PinConfigs" entry out of Info.plist OSBundleLibraries in AppleALC.kext and remove the Plugins folder.

If you put a plugin-less AppleALC.kext and PinConfigs.kext to /EFI/OZ/Darwin/Extensions/Common separately, will they work? (Currently not interested in BIOS flashing).

Now work perfect on Ozmosis!!!!

How to make this work with ALC292?

Thank you!

reasonable, changed for 1.0.6

LockDown · March 29, 2016

I think Calibre was referring to this:

ML_support.tiff

vit9696 · March 29, 2016

Where is that? I thought pretty much everywhere it is 10.9 and newer.

LockDown · March 29, 2016

yeah, all are 10.9+

But he's saying to bring it down to 10.8 for ML support in codec

vit9696 · March 29, 2016

This is not possible without testing. If he wants it — he should be making pull-requests with proven results.

Just take "as.vit9696.PinConfigs" entry out of Info.plist OSBundleLibraries in AppleALC.kext and remove the Plugins folder.

i integrated piconfig.kext in AppleALC's plist. Thats 1 kext less on my hack Great project!!

unexpected_eof · March 30, 2016

Can you please attach the new plist?

LockDown · March 30, 2016

AppleALC_modded_plist.zip

cecekpawon · March 30, 2016

Hmm cc: @crusher

unexpected_eof · March 30, 2016

I can confirm: stripped version 1.0.6 (without plugins) and modded plist works great in EFI folder for Ozmosis

Lol

yup I know for that.

Just tried this on my Asus Z97-A Mobo (uses ALC-892), and it worked perfectly (for line out, not tried optical yet, will do soon).

Thank you!

A quick followup and question. I've just moved my 5.1 speakers to my computer and have it wired both for 5.1 analogue and also optical cable as well. Both work great in Windows but on OSX both sound devices only offer two channels. Is the only way to change the layout-id by generating a new DSDT? Can I use the clover config to auto patch the dsdt? If so is that using HDAInjection?

~~Cheers for the text. Unfortunately it appears to cause a kernel panic on boot. (I have a screengrab but its on my phone)~~

~~-- EDIT I removed the FixHDA_8000 option and I am able to boot again. --end~~

~~I was wondering if you had any thoughts, this is my config.plist:~~

.FixHDA_8000
Renames AZAL to HDEF or HDAU. Adds the HMDI device if absent. Else AppleHDA will not work. Adds the properties "layout-id", "MaximumBootBeepVolume" and "PinConfigurations".

tarasis · March 30, 2016

Turns out I was starting from a false position. I thought I had reverted the system to how it was before using HDAEnabler; turns out i hadn't and I was wrong thinking that AppleALC was working for me.

I've now reverted it properly (clean AppleHDA from my MBP, removed an HDAEnabler.kext I had missed) and tried rebooting with AppleALC but it doesn't appear to work for me. I will dig in, and enable debug information.

Booting with AppleALC and just the Audio - Inject gets sound to work, though only 2 channels.

AppleALC will not work if no HDEF and wrong choice of layout-id even if its loaded

Okay, yeah as long as I include the Audio Inject section in config.plist (be it with a 1, 2 or 3 that the ALC892 supports) then then audio outputs appear correctly in Settings (though only ever having 2 ch available according to the Audio Midi Setup).

If I leave out the Audio-Inject section then no outputs are available in System Preferences->Sound->Output

blackosx · March 30, 2016

Just found some time to test this out and wish to report success.

For ref: Using Toleda’s patches for ALC889.

Working from:

- /S/L/E

- /EFI/CLOVER/kexts/10.11/

- /Efi/Oz/Darwin/Extensions/Common/

Thank you for your hard work vit9696

wern apfel · April 2, 2016

@vit9696 and devs.

Is it ok if we share this kext with own edits at other forums?, of course with the link to the source code.
