ALC262 Lion only

[robi62]

Hi I downloaded alc262 for Lion

but If I install it then I cannot get sound out of speakers

Internal mic works fine

 

This is dsdt patch for it

 

 

Device (HDEF)

{

Name (_ADR, 0x001B0000)

Method (_PRW, 0, NotSerialized)

{

Return (Package (0x02)

{

0x0D,

0x03

})

}

 

Method (_DSM, 4, NotSerialized)

{

Store (Package (0x0C)

{

"CodecAddressMask",

Buffer (One)

{

0x61

},

 

"device-id",

Buffer (0x04)

{

0x3E, 0x3A, 0x00, 0x00

},

 

"MaximumBootBeepVolume",

Buffer (One)

{

0x40

},

 

"layout-id",

Buffer (0x04)

{

0x0C, 0x00, 0x00, 0x00

},

 

"PinConfigurations",

Buffer (0x10)

{

/* 0000 */ 0x30, 0x01, 0x10, 0x90, 0x40, 0x00, 0x21, 0x01,

/* 0008 */ 0x20, 0x00, 0x81, 0x01, 0x10, 0x01, 0xA0, 0x90

},

 

"platformFamily",

Buffer (One)

{

0x00

}

}, Local0)

DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))

Return (Local0)

}

}

 

And this is my hdef from dsdt

 

 

 

 

 

Device (HDEF)

{

Name (_ADR, 0x001B0000)

OperationRegion (HDCS, PCI_Config, 0x54, 0x04)

Field (HDCS, DWordAcc, NoLock, Preserve)

{

, 15,

PMES, 1

}

 

Name (_PRW, Package (0x02)

{

0x0D,

0x03

})

Name (_PSC, Zero)

Method (_PS0, 0, NotSerialized)

{

Store (Zero, _PSC)

If (LAnd (HDWA, LGreaterEqual (OSTP (), 0x40)))

{

Store (Zero, HDWA)

Sleep (0x01F4)

}

}

 

Method (_PS3, 0, NotSerialized)

{

Store (0x03, _PSC)

}

}

 

I tried adding only Method (_DSM, 4, NotSerialized)

 

also I replaced my hdef completely with the patched one but result still the same

internal mic working in system prefs it shows internal speakers but no sound at all.....

 

How can I Fix it?????
