HDMI AppleHDA and DSDT Patch Thread

[blueking]

An alternate DSDT edit for HDMI audio. I've successfully tested a generic HDMI audio DSDT edit (credit to tmongkol http://www.insanelymac.com/forum/index.php?showtopic=205802&st=360 ) The installation is the same as described on tonymacx86's blog http://tonymacx86.blogspot.com/2010/10/hdmi-audio-video-solutions.html . I've tested this HDMI audio DSDT edit on the GT 240 and the HD 5870. Yes, the same edit appears to work with both Nvidia and ATI graphics cards with native HDMI or DisplayPort.

Would this work on an hd 3000?

No, GFX0 and HDAU only works with discrete graphics cards that have a dedicated audio codec. dsdt edits for HD3000 HDMI audio are described here http://tonymacx86.blogspot.com/2011/09/hdmi-audio-solutions-intel-hd-3000.html. New Lion HDMI Audio Guides will be available in the next week or so.

As my speakers require voodoohda, that doesn't really apply much to me.

So could I do this http://www.projectosx.com/forum/index.php?showtopic=355

and then would it work? Or would I also need to do the dsdt edits?

I have no experience with Voodoo. The Intel HDMI codec_id is 8086 2805, this is addition to the motherboard codec. If it shows up in IOReg/HDEF/Voodoo, you may have some probability of getting it work. The pinconfig for HDMI audio is <e0 00 56 28>. Good luck.

Ok. How would I write the pinconfig then? like 0x285600e0 or did I do it wrong?

I realize you say you don't have experience with voodoo, but I think you can probably help with this part. How do I find the codec number? and the node? This is an example one below. And would the device id for hdmi audio be listed under intel display audio in device manager in windows? I will get out of your hair after this.

<key>Codec</key>
<integer>2</integer>
<key>Config</key>
<string>0x90a6e140</string>
<key>Node</key>
<integer>19</integer>

I have no idea what the above means, sorry. You should see the HD3000 audio codec in sound device manager.

Without successful dsdt edits, HDMI audio will not work. Try this guide http://www.tonymacx86.com/viewtopic.php?f=162&t=22028
