No Audio Devices - Realtek ALC AppleHDA [Guide]

missed more than half of it!

AppleHDA.kext is damaged and unusable. Use MultiBeast 7.5.

1. Description of audio problem: Originally, I booted using the Clover config.plist from the tonymac Yosemite guide and then running audio_cloverALC-110_v1.0f.command returned this error:
   

   [COLOR=#000000]EFI partition is mounted[/COLOR]
   [COLOR=#000000]Boot/Arguments = kext-dev-mode=1 found[/COLOR]
   [COLOR=#000000]Error: no IOReg/HDEF; BIOS/audio/disabled or ACPI problem[/COLOR]
   [COLOR=#000000]No system files were changed[/COLOR]

   I made sure audio is on in the BIOS (the only relevant setting I see is Integrated Peripherals->Azalia Codec->Auto). So I then tried again - this time I replaced that config.plist with a fresh vanilla config.plist the Clover v2.3k_r3270 installer created, and rebooted. Now, audio_cloverALC-110_v1.0f.command gives this error:
   

   [COLOR=#000000][FONT=Verdana]EFI partition is mounted[/FONT][/COLOR]
   [COLOR=#000000][FONT=Verdana]Boot/Arguments = kext-dev-mode=1 found[/FONT][/COLOR]
   [COLOR=#000000][FONT=Verdana]
   [/FONT][/COLOR]
   [COLOR=#000000][FONT=Verdana]No audio codec detected[/FONT][/COLOR]

   So, I followed the No Audio Devices troubleshooting guide, which (if I followed correctly) indicates I need to "add HDEF". Following that guide, I get as far as layout-id <00 00 00 00>, which says "not valid", and the instructions seem to end there. So even though my motherboard has ALC889a, I cannot use cloverALC to get audio working in Yosemite? Am I using the wrong version, or the wrong script entirely? Please point me to what I'm missing. Thank you!

Sorry, doesn't work. Just tried it. Now (after installing it) I can't even find it where it supposed to be (library extensions)

dsdt?

No DSDT. I had followed a short guide someone with the exact same motherboard posted, and he mentioned he was running successfully without a custom DSDT, that Clover was handling all that via injection.

Does it sound like my board requires a DSDT for this after all?

 

[toleda]

No DSDT.

OK. Codec is not enabled, no audio until you see DPCIManager/Status/Codec ID

OK. Codec is not enabled, no audio until you see DPCIManager/Status/Codec ID

Ok...er, does this mean I must use a DSDT then? And if so, any idea how that other guy got his audio working with your script - on a board identical to mine - without a DSDT?

Thanks so much for your help (and patience)!
