Hey everyone, I have one problem to ask you. My system consists like this. and my kernel is Darwin 8.11.1 (EFI, GUID, Vanilla). The problem I have is sound problem. When I use with external AC adpater on my hackin-macbook, my sound card sounds clearly. But when I take it off and only use hackin-macbook by battery, it sounds noisy.

I used both AppleHDAPatcher and AzaliaAudio. But no one works.

What's the problem with my hackintosh? Does anyone has solution?

Model : Haier W59 (CM440)
SoundCard : ALC883 (Built-in)
O/S : OS X 10.4.11 Tiger (XxX 10.4.11 Rev.2)
