Input Gain starts at 80

[Mikebyrne000]

Hi, 

 

When I boot the machine the speakers make a hissing sound. To correct this, I launch VoodooHDA, select AppleACPIPlatformExpert/PCIO@0/AppleACPIPCI/HDEF@1B and slide input Gain to 0

 

I have tried editing the plist to the following: /System/Library/Extenstions/VoodooHDA.kext

It's set to 0 but still launches at 80. I assume i have edited the wrong file??

 

Any help would be great!

Use utility "voodooHDAsettings"

[Mikebyrne000]

I can slide down input gain to 0 from VoodooHDA settings 

 

But everytime I reboot it goes back to 80 

 

It doesn't seem to save
