EDIT: sorry for bad formatting....

 

Stereo out tested; spdif light on, not testing. no other configs tested

 

This still needs taruga's AppleHDA kext patching, but removes need for ALCInject.

 

END EDIT

 

Intel D975xbx2kr BadAxe2

Sigmatel 9274D

 

use at your own risk.

 

a) install STAC9274D_83847621.txt using Taruga's AppleHDA Patcher 1.16 fix perms, reboot; confirm sound works

 

b ) MOVE /S/L/E/AppleALCInject.kext to /backups (e.g. only. ie. SAVE your environment)

 

c) BACKUP /L/P/SC/com.apple.boot.list and remove extensions.mkext

 

d) using instructions from:

http://forum.netkas.org/index.php/topic,104.0.html obtain a GFX-string plist if you do not have one for your video card. if you do not need one, a template SFX plist is found in that thread

 

e) add the following data to GFX-string plist for STAC9274D sound chip:

 

		<key>PciRoot(0x0)/Pci(0x1b,0x0)</key>
	<dict>
			<key>PinConfigurations</key>
			<string></string>
			<key>built-in</key>
			<string>0x00</string>
			<key>layout-id</key>
			<string>0x0000000c</string>
			<key>revision-id</key>
			<string>0x00000001</string>
			<key>subsystem-id</key>
			<string>0x00000419</string>
			<key>subsystem-vendor-id</key>
			<string>0x00008086</string>
			<key>vendor-id</key>
			<string>0x00008086</string>
	</dict>

 

f) build hex string and replace existing one in com.apple.Boot.plist

 

reboot and hope it works like mine does

 

now, i notice some #s are different from linux codec dump. i will see if this allows line/etc if i can fix. if not. too bad :(

 

hex string for 7600GS+STAC9274D:

this stupid stupid stupid forum software makes it very difficult to want to contributeok.

 

edit # a gazillionnow

 

NOT quoted as code, but attached is the SFX plist string

 

attached as txt is the codec dump from ubuntu linux 7.10

 

my first question is why the plist does not have sigmatel as the vendor-id or subvendor-id but only intel (8086)

 

.wonder if changing that would remove need for the taruga patch

 

2nd question: the codec revision # is also different from the value in the plist

 

more reboots are in order ...

 

question to mods: why heck does "add reply" , or "fast reply", or clicking on my post and hitting "reply" RANDOMLY _*NOT*_ actually ADD a reply, but MERGE with my previous one?

 

very frustrating.

EFI string definitions

 

Hello,

 

Does anyone know of a good source for the definitions used in the audio portion of the XML plist files?

 

 

My Badaxe2 Sigmatel linux audio codec has the following:

 

Codec: SigmaTel STAC9274D

Address: 2

Vendor Id: 0x83847621

Subsystem Id: 0x80860419

Revision Id: 0x100201

 

 

I've used the following values with stereo out success:

 

<key>layout-id</key>

<string>0x0000000c</string>

 

<key>revision-id</key>

<string>0x00000001</string>

 

<key>subsystem-id</key>

<string>0x00000419</string>

 

<key>subsystem-vendor-id</key>

<string>0x00008086</string>

 

<key>vendor-id</key>

<string>0x00008086</string>

 

 

 

 

Does "layout-id" correspond to "address"?

 

Would a better value for "revision-id" be 0x100201?

 

Would a better value for "vendor-id be 8384?

 

Thanks

*) I can only test stereo out and mic in

 

using taruga's patched AppleHDA environment:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 

a) changing "revision id" to 0x100201 (from codec dump)

 

had no adverse impact, still no mic in, so i left it in

 

B ) changing vendor-id or subsystem-vendor-id from 8086 (intel) to 8384 (sigmatel audio) had adverse impact (no sound) -- so i revert.

 

c) I've noticed taruga's kext includes layout xml files under Resources/ subdir numerically named

 

all have "spdifin" or "spdif_in" _except_ layout6.xml and layout7.xml. badaxe2 does _NOT_have spdif input BUT gfxstring's input plist uses layout-id 0xc (ie. 12 decimal).

 

changing to 6 or 7 and regenerating EFI string had adverse impact (no sound). so i revert.

 

d) then noticed AppleHDA's info.plist file ALSO has LayoutID set as 12 (0xc) but its different from contents of layout12.xml so i am not yet sure how to plug layout6.xml or layout7.xml into Info.plist

 

hopefully a clue for someone else.

 

so this evening concludes 5 hours of edit/reboot.

 

maybe more work on the weekend.
