@panner Try disabling "Runtime Power Management" in your BIOS if you have that option. This is a common issue and cannot be resolved unless you want to invest into some PS2/ACPI coding which i do not recommend.

You can always click the "apple" logo and click hibernate/sleep there.

 

As for your Audio, try downloading another VoodooHDA.kext, and install with kext wizard. If you have crackling sound after installing kext, perform the following edit to solve this;

 

-Right click VoodooHDA.kext and click "Show package content"

-Click contents and rightclick info.plist -> open with texteditor.

-Edit the following lines and save/reboot when you're done;

 

<key>CFBundleShortVersionString</key>
<string>2.9.2</string>

<key>CFBundleSignature</key>
<string>???</string>   <--- replace ??? with build number e.g 292 (you can see your build number in the string above, it may vary)

 

<key>DTSDKName</key>
<string>???</string>  <--- replace ??? with build number e.g 292

 

<key>AllowMSI</key>
<true/> <--- Set this to false

 

<key>InhibitCache</key>
<false/>  <--- Set this to true

 

<key>PCM</key>
<integer>90</integer>  <--- Set to 99
<key>Rec</key>
<integer>90</integer>   <--- Set to 0
<key>iGain</key>
<integer>90</integer> <--- Set to 100
<key>iMix</key>
<integer>90</integer>  <--- Set to 0

 

<key>Vectorize</key>
<true/>  <--- Set this to false

 

now reinstall your patched VoodooHDA with kext wizard and reboot again.
