clearing up some error messages

[SgtArky]

I have pretty well function computer now. I just want to clear up some error messages. And I would love to increase the sound volume...its a little low.

here is one of the error messages I get, when running dmesg

IOSurface: buffer allocation size is zero

 

and some more.

 

 

kxld[com.yourcompany.driver.AppleACPIPS2Nub]: The Mach-O file is malformed: Invalid magic number: 0xfeedface.

Can't load kext com.yourcompany.driver.AppleACPIPS2Nub - link failed.

Failed to load executable for kext com.yourcompany.driver.AppleACPIPS2Nub.

Kext com.yourcompany.driver.AppleACPIPS2Nub failed to load (0xdc008016).

Failed to load kext com.yourcompany.driver.AppleACPIPS2Nub (error 0xdc008016).

Couldn't alloc class "AppleACPIPS2Nub"

Tra to delete this kext. Sometimes it isnt needed. (I have PS2 things also, but i don't have any PS2NUB kext).

[Gringo Vermelho]

The error message says that it doesn't load anyway, so if everything works without it then it should be safe to delete it.

You are using VoodooHDA for sound, correct? Open Terminal and type:

 

sudo nano /System/Library/Extensions/VoodooHDA.kext/Contents/Info.plist

 

and scroll down to these two lines:

<key>VoodooHDAEnableHalfVolumeFix</key>
<false/>

and change it to:

<key>VoodooHDAEnableHalfVolumeFix</key>
<true/>

[SgtArky]

i don't have those lines.

[PookyMacMan]

You do if you have Voodoo. Post your VoodooHDA plist file up here.

You're using an ancient version of VoodooHDA (0.2.1). Use this version (2.7.2) and enable the half volume fix.

i deleted AppleACPIPS2Nub.kext now I cant log in, apparently that kext is for my keyboard. mouse works. I wonder how I am going to get back in and fix it?

[PookyMacMan]

Can't suggest much other than reinstalling or plugging in a USB keyboard/mouse.

IOSurface: buffer allocation size is zero

This is an error with Adobe flash player, there is a bug filed with Adobe, there is also a thread with a poll on here somewhere.

If you want to add your vote to the bug tracker there is a link within the thread.

oh i finially got back in, I learned how to use my install usb, and mounted the drive and move the files, but the keyboard still didnt work. So I booted it arch=i386, it started working again, then I booted back in x64 and everything is fine. The voodoohda was updated, and modified. I still dont see much difference in sound, now youtube videos have no sound at all.

[PookyMacMan]

Did you update caches?

 

When you change a kext's plist file like that, you have to run Kext Utility or a similar program to update the kext caches; otherwise the changes don't work.

[SgtArky]

yup i ran Kext util

[SgtArky]

sound is still {censored}.
