ALC889 Sound Assertion Errors

[ebr4him]

Hi,

I'm using drivers from MultiBeast for ALC889 and they work okay (the notification sounds are usually delayed by a second or so), but its spamming my console with:

kernel[0]: Sound assertion in AppleHDAController at line 8088

...couple of times every minute!

Are there better drivers available or a way to fix it? Ofcourse, I've searched before posting but couldn't find a solution.

Many Thanks!

Not enough information.

Ok, I installed Patched AppleHDA using MultiBeast cause I already use DSDT for my motherboard (Z68XP-UD3R) from Tony's DSDT Database.

Audio works but the delay is sometimes annoying but especially these sound assertion errors:


28/07/12 4:41:00.000 PM kernel[0]: Sound assertion - Command/Response TIMED OUT and ( kRequestStateMatch == fCodecRequest->state = 2 ), fCodecRequest->command->codec: -549428886272, fCodecRequest->command->verb: 0xFFF, fPoweredDown: 0

Is there any other information I should provide that might help you in determining the issue?

thanks!

Is there S/L/E/ALC8xxHDA.kext or HDAEnabler... installed? Reply with a copy of IOReg. [Guide] How to Make a Copy of IOReg

Since I don't have xcode installed (will take me a day on slow connection!) can I use DSDTSE?

Use the IOReg link above. You don't have to install Xcode. DSDTSE is fine but read the link.

I downloaded and copied to the Applications, on running it just runs the beach ball spinner endlessly.

Ah Sorry, didn't see you attached the working version.

Please find oreg attached.

Please find oreg attached.

Don't see any problems. Suggest clean install when convenient.

Ah, OS re-install?
