Well I hope I ain't bumping a thread that is completely dead since I jumped on this bandwagon rather late... for everyone that is having an issue with the hissing noise, I figured out a permanent fix. I am a n00b w/ hackintosh so it may not fix every single persons problems


Copy the voodoohda.kext from the general extensions folder, paste on desktop.
Right click, show package contents, open info.plist with a text editor (if you use xcode just add a string to mixer values called iGain with 0 as a value) and where you see the following

<dict>
<key>iMix</key>
<string>30</string>
</dict>

Well just add a string to it, in the end it looks like this... essentially add any of the mixer names and the default value following this format.

<dict>
<key>iGain</key>
<string>0</string>
<key>iMix</key>
<string>30</string>
</dict>
hit save
and magic.... paste it back in the general extensions folder over the old version, run the updateextensions, and reboot... hissing noise gone, everything works perfect so far audio wise.

If you have a ralink wireless n adapter... do whatever you can to get rid of it, just my advice. It causes random kernel panics on sleep, and does not support wpa enterprise, which is what my college uses and renders the netbook almost useless on campus. thank you for the idea of creating a shared partition though, I was about to just use ntfs-3g or whatever.
