I have contacted the dev team, but still waiting for a reply.
Do I need to keep XCODE installed in order for this to continue working? I would like to free up the GB if I can
No, you don't.
The volume from the computer speaker is really low - even when it is turned up - when I plug the headphones in its crystal clear loud. I think I can fix it in the preference pane - but thats not working
You cant increase the volume directly into the table.h source code, at the end of this file, then build your kext again (don't forget to delete the kext folder before doing this again). Check out my post here to see what I mean to increase the volume, or you can directly download my build.
When I click the VOODOO HDA icon in the preference pane I get the following error:
ERROR Can't Map Memory.
When I try to move the sliders it gives the following error:
ERROR Can't connect to StructMethod to send commands
That mean you didn't installed the provided kext given with the pref pane. Actually the voodoohda source code they give on their dev website is not the one compatible with the pref pane tool they provide. So don't try to use the pref pane. But you can if you want download the right kext here: http://forum.voodoop...opic,139.0.html (download the second file)... but for me my build is better.
