barat Posted October 23, 2012 Share Posted October 23, 2012 Hello, I have a problem like in topic. I can't make my ALC888 working... I found this entry: http://www.insanelymac.com/forum/topic/280468-applehda-patching-in-mountain-lion/page__st__60#entry1840394 But patching isn't only thing I have to do i think ... i foud info that i need files like layout12.xml, info.plist, platrofms.xml but I don't know how to get them ... I realy want to do patching etc myself but I even doesn't know how to do this and how to get proper files. On SL 10.6.8 my sound was OK - everything worked (all line ins/outs) and all 5 speakers in my laptop worked ... I made DSDT like this: Device (HDEF) { Name (_ADR, 0x001B0000) Method (_DSM, 4, NotSerialized) { Store (Package (0x08) { "subsystem-id", Buffer (0x04) { 0x0D, 0x3A, 0x00, 0x00 }, "subsystem-vendor-id", Buffer (0x04) { 0xAA, 0x17, 0x00, 0x00 }, "layout-id", Buffer (0x04) { 0x0C, 0x00, 0x00, 0x00 }, "PinConfigurations", Buffer (Zero) {} }, Local0) DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0)) Return (Local0) } Method (_PRW, 0, NotSerialized) { Return (GPRW (0x0D, 0x03)) } } And used kext from this guide (in Polish) http://forum.osx86.org.pl/topics33/lenovo-y530-poradnik-instalacji-mac-os-x-1068-vt5036.htm Then I made upgrade to ML 10.8.2 and - no sound, and I can't get it back ... Can someone help me? Link to comment Share on other sites More sharing options...
fantomas Posted October 23, 2012 Share Posted October 23, 2012 Hi and what about VoodooHDA.kext ? Link to comment Share on other sites More sharing options...
barat Posted October 23, 2012 Author Share Posted October 23, 2012 Voodoo is some kind of substitute for AppleHDA I think ... its only a walk around. If there will be no other way I'll think about it, but after I had "native" AppleHDA on 10.6.8 it's hard for me to think about something that isn't the real sollution... It's like with the battery status indicator - I have hardware indicator under screen (5 LED), but even so i would edit my DSDT to have it bak near clock on top bar Link to comment Share on other sites More sharing options...
