HDMI audio with unsupported alc chip and gfx card sound chip

[styrian]

Hello!

 

Besides the by Toleda supported method for HDMI audio ( http://www.insanelymac.com/forum/topic/292999-mavericks-applehda-hdmi-audio/ ) there seems to be a working solution, if you can get HDMI audio not working with Toleda´s method:

 

Basic requirement to get this solution working,  is using an untouched vanilla IOAudioFamily.kext (Epadfix or codeccommmander seem to work, if needed) & working AppleHDA.kext.

 

Enabled HDMI key in Bootloader and/or correct HDMI edits in DSDT/SSDT.aml.

 

You should try, if voodoohda 2.8.6 is recognizing your soundchip on your gfx card oob. For trying this just install temporary applehdadisabler.kext and voodoohda.kext. If it is working for hdmi you have two choises to get applehda and voodoohda working side by side at the same time. (If VoodooHDA is not working oob, node edits for hdmi ports are necessary)

 

The first is to change in the Info.plist of AppleHDADisabler.kext (I have renamed it to AppleHdmiDisabler.kext) and VoodooHDA.kext the following key:

 

           <key>IOPCIClassMatch</key>

           <string>0x04020000&0xFFFE0000</string>

to

 

           <key>IOPCIPrimaryMatch</key>
            <string>0x########</string>

 

Replace ######## digits with the ones of Device ID and Vendor ID of your gfxcard soundchip, found in SystemInfo.app or DPCIManager.app.

(Preferred solution, if Clover does on the fly binpatch of AppleHDA)

 

 

 

If this is not working for you or you are using a prepatched AppleHDA.kext, do the above edit only for the Info.plist of VoodooHDA.kext and the following edit in the Info.plist of AppleHDAController.kext (PlugIn of AppleHDA.kext):

 

           <key>IOPCIClassMatch</key>

           <string>0x04020000&0xFFFE0000</string>

 

to

 

           <key>IOPCIPrimaryMatch</key>
            <string>0x####8086</string>

 

Replace #### digits with the ones of Device ID of your  alc soundchip, found in SystemInfo.app or DPCIManager.app.

 

 

I´ll hope, that you are able to get HDMI sound also working in this way.

 

Have fun.

Without using a gfx card your statement seems to be true and my solution is not needed, if you can get Hdmi sound working in an other way.

 

Have fun.
