Lenovo Y530 ALC888 ICH9 on 10.8.2 - no sound

[barat]

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?

Hi

 

and what about VoodooHDA.kext ?

[barat]

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
