IDT Audio project.

To have vanilla AppleHDA we need to patch it with IDT audio codec. Here's a guide for snow leopard. If someone wants to try it, is all explained here.

It's quite a bit old.

HDEF is in the DSDT, so if we can edit the latest Lion AppleHDA in this fashion- it will be much better than VoodooHDA.

Thanks Tony for your support.

I've tried using bcc9 perl script for IDT patching and swapped with his layouts but so far without any success.
I attach below my linux codec dumps, verbs and codegraphs for anybody to try.

Useful tools:

Linux HDA-Analyzer (real time node testing)

Windows 7
hdau.exe (pin validation and real time graph)
http://msdn.microsoft.com/en-us/windows ... e/gg462977
(remember to rollback to windows default drivers for both codecs. Will not work with HP or Intel)

I'm definitely excited to get better sound. And hopefully HDMI audio as well!

I can't help much in terms of solving, but I definitely will test. I have a partition I can completely screw up.

This is the same codec as on HD 3000 for desktop CPUs- and the same one as in the macbook air, and mac mini. It's already solved! So HDMI audio out should work with an HDMI cable plugged at boot time and a few minor DSDT edits.

So we can't have HDMI audio if its plugged in after boot?

Ya- with some minor DSDT edits- check out toleda's guide here:

Slightly confused. A few posts ago you said "So HDMI audio out should work with an HDMI cable plugged at boot time and a few minor DSDT edits."

So you're saying by following toledo's guide we can use it, even if it isn't plugged at boot time?

Oh, gotcha. Sounds good! I'm looking forward to seeing how else you can improve this!
