Strange sound from speakers when I use software mute

[toology]

When I mute the sound via OSX volume settings, I get a THUMP sound as if I manually unplugged speakers from the sound card while turned on. This also happens when starting OSX. Otherwise the sound works normally

 

I am using the integrated Analog Devices AD1988A codec from my Asus P5B motherboard, VoodooHDA.kext is installed through iATKOS S3 v2 (my distro). I also have a Sound Blaster Audigy 2 ZS Pro, but I still haven't dared try kX drivers for OSX.

 

I know this is a very small issue, but I wanted to see if perhaps it is easy to fix.

I have pretty much the same problem, but my sound sounds ALWAYS like that. I haven't managed to fix it yet.

Remove irqs-> pic and tmr devices, the problem may be that!

 

can apply this patch

use the DSDT EDITOR AND PATCHER

Thanks for your reply, but Ill have to do some major research about DSDT editing before I can use that info.

 

I literally installed OSX with only 4 aditional kexts + default on iATKOS S3, everything works except sleep, front usb ports and this bug.

DSDT EDITOR and PATCHER --> greatly facilitates

 

in many cases a different version of the kext solves the problem

but we must apply this fix anyway
