Audio ALC888 and 5.1 channels , patch AppleHDA.kext

1 post in this topic

Recommended Posts

Hello

 

 

I'm have problem in Mountain Lion with sound on ALC888 in EP41-UD3L and not run audio 5.1. Only 2 channel works - screen photo file I add to this post. Now use this file

https://www.dropbox....pleHDA.kext.zip

 

 

 

In Lion, my sound was working perfectly using only AppleHDA + Plataform.xml + layout888.xml all added with HDA Wizard (link to this files:)

For Mountain Lion I make this (and not works for me - is't audio):

You need to rename layout888.xml to layout12.xml and edit inside layout12.xml to be as following

 

<key>LayoutID</key>

<integer>12</integer>

 

get perl script from zlib.pl.zip (by Revogirl, R.I.P.)

 

(compress)

perl zlib.pl deflate layout12.xml > layout12.xml.zlib

 

 

also;

perl zlib.pl deflate Platforms.xml > Platforms.xml.zlib

 

copy *.xml.zlib to /System/Library/Extensions/AppleHDA.kext/Contents/Resources/

And link to oryginal (not patched) AppleHDA.kext for Mountain Lion :

    • Nice @yapan4 then we can join forces to make this as good as possible.
    • I had a weird situation, after running great for a while: yesterday I did a reboot and got a KP. Turns out the AstekFusion2Adapter kexts were causing the KP, strange thing is I didn't recall applying any update or a like.  I had to boot with the USB installer, mount the EFI partition to delete the old AstekFusion2Adapter kexts and replaced with the patched version contributed by despeinao. I'm glad the system is working again, not having to reinstall OSX.
    • i think the "red light" you are referring to is that you have a optical SPDIF output (3.5 mm) combo jack. it most likely will be "red" when audio is active. 
    • Domanda , ma il tuo configplist lo ha settato cosi Gengik????
      Noto molte cose atipiche , tipo aperto con Clover configurator nella sezione ACPI il nome DSDT.aml NON è selezionato , quindi in teoria NON dovrebbe caricare il DSDT che hai in Clover ACPI Patch , se usi SSDT x la CPU NON dovrebbero servirti quelle personalizzazioni sempre in configplist sezione CPU ...
      Secondo me dovresti partire da un configplist pulito , xche sempre secondo me c'è rimasto delle schifezze di qualche tool x installare facile    EDIT
      Scaricando il configplist di jolly NOTO ha impostato +o- come intendevo fare io , sistemando quello  sopra elencato e bammmmm NON avvia , mi forniresti x favore Hack info che trovi nella mia firma ???
      Grazie   Ho creato un configplist , se vuoi provare , dovrebbe essere pulito da ogni impurità , se funziona dovrai adattarli tutte le tue personalizzazioni x il boot ..... config.plist.zip
    •   Can you share the Clover folder that lets you boot?
