Sound assertion problems

Mobo: DSDT-GA-Z68X-UD3H-B3

 

I'm using DSDT and ALC889 driver and getting the following errors:

Sep 20 15:06:37 liondev kernel[0]: Sound assertion - Command/Response TIMED OUT and ( kRequestStateMatch == fCodecRequest->state = 2 ), fCodecRequest->command->codec: -549449031168, fCodecRequest->command->verb: 0xFFF, fPoweredDown: 0Sep 20 15:06:37 liondev kernel[0]: Sound assertion in AppleHDAController at line 5097

Those errors appear when I try to playback sound. There is a delay of few seconds on playback and then assertions.

hello

 

alc is not native in mac os x ...

 

so expect always some sound assertions with patched applehda for u alc..

 

u know any mac u use alc889 ? so for that u must patch the kext..

 

only know 2 options for sound in mac ox x

 

applehda

 

voodoohda

 

u can always try to use voodhda

 

good hack

I solved the problem with installing ALC8xxHDA and HDAEnabler from GA-Z68X-UD3H-B3 pack.

Also upgraded bios to F12, not sure if this is related though.

No more assertions.
