Audio problem ALC892, scratch sound after pause

[Fliand]

Hello everyone! Actually I'm new in Hackintosh, I have a problem with my sound. I use toleda+clover audio solution, my codec is ALC892, Clover define my system as iMac13,2. As you know this system definition has a specifically feature - it turns off an audio system after a sound pause, so I can hear a scratch sound for a while(just half second or one second) after its turning off or turning on. But if sound keeps playing, then there is no scratch, and the sound is fine.

I can solve it by changing my system definition to MacPro3.1 cause audio system will work all the time using this system definition, but this way I will have a problem with no sound after sleep and as I know I wont be able to make AGPM for my graphic card cause MacPro3,1 does not have AGPM. Also I can solve it by using Antipop software that prevent audio system turning off. But may be is there any solution of this problem? I mean, maybe there is way to remove scratch sound after audio system turning on or turning off. Please help me.

Please , sorry me for my english, it's not my first language, please ask if anything is not clear.


Yosemite 10.10.3, Clover bootloader.
System definition iMac13.2
intel core i5-3570k
msi z77a-g45 (alc892) AppleHDA toleda

I heard about Antipop. I've tried it. Yes it works, audio system doesn't sleep with that. But there're also scratch sound when computer turns on and turns off, also after exit out of sleep. These are in MacPro3,1 definition either, but it has less loud scratch sound than in iMac13,2 with antipop.

Maybe are there any ways to solve this problem, any ways except antipop and MacPro3,1 definition?

Thanks.
