for your audio, in your config.plist, you need to set these to "true"
Code:
<key>Fixes</key>
<dict>
<key>Comment-IRQ Fix</key>
<string>The following fixes may be needed for onboard audio/USB/etc</string>
<key>FixHPET</key>
<false/>
<key>FixIPIC</key>
<false/>
<key>FixRTC</key>
<false/>
<key>FixTMR</key>
<false/>
</dict>
and further down, you need to remove the #s:
Code:
<key>PciRoot(0)/Pci(0x03,0)</key>
<dict>
<key>#hda-gfx</key>
<string>onboard-1</string>
<key>#layout-id</key>
<integer>3</integer>
<key>#no-controller-patch</key>
<integer>1</integer>
</dict>
<key>PciRoot(0)/Pci(0x1b,0)</key>
<dict>
<key>#PinConfigurations</key>
<data>
</data>
<key>#layout-id</key>
<integer>3</integer>
</dict>
after you reboot, you should have audio working, if not, then look above to where layout-id is set to 3, you may need to change this to whatever will work according to:
