sound assertion errors

[robydream]

i have ALC662 and all is working perfect except sound assertion errors at boot...could some one give me a clue where to start searching or how to fix it

 

i only get two errors:

 

11/21/10 12:39:36 PM kernel Sound assertion "0 == pathMap_aDriverInstance" failed in "/SourceCache/AppleHDA/AppleHDA-184.4.3/AppleHDA/AppleHDADriver.cpp" at line 1666 goto Exit

 

11/21/10 12:39:36 PM kernel Sound assertion "0 != createAudioEngines ( fPathMap_aDriverInstance )" failed in "/SourceCache/AppleHDA/AppleHDA-184.4.3/AppleHDA/AppleHDADriver.cpp" at line 203 goto Exit

 

so i could not find sourcecache to get on line 1666 and 203 to find where is the error.possible syntax for injecting is bad?

 

i use dsdt injecting and legacyHDA kext to inject pinouts.

 

any help is welcomed...

 

many thanks.

Hello....i have found solution to get rid of sound assertion errors.... yupiii....

 

Here is SOLUTION:

 

Under Device (HDEF) add these two parameters to inject:

 

"CodecAddressMask",

Buffer (One)

{

0x01

},

 

"platformFamily",

Buffer (One)

{

0x00

}

 

"PinConfigurations",

Buffer (0x20)

{

*** YOUR PINCONFIG FROM LINUX AUDIO CODEC DUMP ***

}

 

compile to dsdt.aml place dsdt.aml to E/E folder...and sound assertion errors is gone....ofcorse you need legacy kext with pinconfig...now i study how to inject all data from legacy kext to dsdt.

 

cheers..:
