No Audio Devices - Realtek ALC AppleHDA [Guide]

[pyraylos]

hi toleda. i have no audio devices in system prefs/sound/output. i have alc892, audio id 1, no dsdt, and i run multibeast 7.0.2 and chose the alc892 option, but i got no output devices. could you help me configure correctly my audio?

I assume that there is no problem in the apple hardware.

Native AppleHDA.kext problem means native hardware has the problem, see Apple Forums. The 10.9.2 sleep fix broke wake audio on some non native systems. Another fix is unlikely.

3. did several different methods. as suggested to use multibeast to redo the install, choosing the ALC1150 driver (also tried the ALC1150 driver with Optional 3 Port Audio, and ALC1150 driver with Optional HDMI Audio)
9. Attached (audio_realtekALC-100.command)

Chimera cannot enable HD4600 HDMI audio
9 is missing; MultiBeast or realtekALC script, not both.

ok here it goes:
1. no audio devices in system preferences/sound/output
2. 10.10 yosemite/asrock p67pro3/intel i5-2500k/gtx560ti
3. procedure: i run multibeast and select alc892 option. rebooted and i had no audio devices. tried the script audio_realtekALC-100.command, it said i had to install native AppleHDA.kext, so i did, rerun the script, rebooted but still no audio devices. then i read this guide. i checked that Drivers/Customize/ Boot Options/Kext Dev Mode was installed. searched for hdef in ioreg but not found. i found @1b, so i followed [Guide]-Add_or_Edit_HDEF-dsdt.pdf. i opened dsdt.aml in maciasl and tried to compile, found 19 errors, added toleda repository, patched Patch/toleda/AMI/Clean Compile, tried to compile again, i got 2 errors. then i posted here.

is there a way to get the native one without having to lose all my apps?
