Hello,

I have a problem like in topic. I can't make my ALC888 working...

I found this entry:
http://www.insanelym...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?

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 ;)
