I installed iDeneb 1.5 (Mac OSX 10.5.7) on my computer, everything works perfect, but the audio gets very lag. If I play an MP3 immediately after the system installation completed, it sounds ok for about a minute, and then becomes lag, and after that, the sound will lag forever, no matter I reboot, remove and reinstall the audio driver, or even change the sound card, it's always lag, unless reinstall the Mac OSX system.

And if i move my mouse cursor around, the sound will become normal, but as soon as I stop moving, it lags again.

What's the matter?

And my computer:

Mainboard: Asus M3A78 with the latest BIOS

CPU: Phenom X4 9650

Memory: 4GB DDR2 800 dual channel (tried using 2GB single channel but the problem is still not fixed)

Sound card: Tried onboard VT1708B with AzaliaAudio.kext, CMI8738, SoundBlaster Live 5.1(SB0060) with kX 1.3b0, all of them get this problem.

During iDeneb installation I chose 9.5.0 Voodoo Kernel, AppleSMBIOS 800MHz, AppleATIATA, Realtek 8169/8111, NVInject 0.2.1, and nothing else.




Anyone knows about this please help me, Thx!!

add idlehalt=0 in com.apple.Boot.plist then everything goes fine.

be aware that your Temp will go Up with that flag though.
