Audio EFI Strings - 12-29-2008, 05:04 AM
Thought I would start a topic for this as I think this might solve the audio wake issue. Here is my post from another topic
On the audio problem I really think the solution is EFI Strings. The problem I am having is I cannot get the xml I have to go to hex code using gfxutil. It says there is a problem. I used the example to make it from http://forum.netkas.org/index.php?PHPSE ... 104.0.html and the graphics one I did (which did not work but is appears to be known issue on dells) worked fine to convert from xml to hex. I see nothing wrong with it.
BTW i double checked with those on the EFI Boot forum and the method I am using DOES support EFI strings is com.apple.boot file on EFI part. If anybody has any ideas please fire away. I have used the tools and gotten the values we need which are below now if I can only get them into hex for the com.apple.boot file ;-)

Have you read this from netkas:
Known to be supported: ALCxxx and Sigmatel (thanks to macgirl). Not sure about the others. However, this guide is mainly for ALCxxx users!
Thanks to tom3q, now we can add support for ALCxxx audio cards (and others!) without using ALCinject.kext. However, you still have to use modified AppleHDA.kext.
In brief, you will have to have a working sound before switching to the EFI method. For best results, use Taruga's AppleHDA patcher to get AppleHDA.kext modified the right way. Refer to the main topic dedicated to that patcher: http://forum.insanelymac.com/index.php?showtopic=32859
Not sure if this is why it fail... maybe you did not patch AppleHDA properly?
