Man, I did nothing except normal reboot ...

I go get the codecs

Just like others here, I'm trying to fix a silent 10.6 machine. My machine is a Clevo M570RU-U, with an ICH8M, and a Realtek 883 codec. I've been through TheKing's procedure to create a patched AppleHDA.kext, adapted to Snow Leopard with the excellent information in this thread. The machine runs 10.6 32bit, since I need functional VMware Fusion.

I tried the easy solution of VoodooHDA.kext, but that does nothing for me, and 'voodoohelper -dump' returns the 'error: IORegistryEntryGetPath returned 0x10000003' error that indicates that Voodoo HDA found no devices functional.

My issue is that I don't see any audio devices, in System Profiler, and, of course, there are no input or output devices available under System Preferences/Sound. This machine never ran 10.5, so I don't have exiting functional codecs to work from.

I am attaching the source for my dsdt.aml, and all the items that were necessary to follow TheKing's document, and the resultant Info.plist files. I'm also attaching the codec dumps. Last, I'm attaching a screen capture from my System Profiler, Audio section.

If anyone has time, and is willing to take a look, it would be greatly appreciated.

Thanks!

@: ajacocks

Why are your kexts empty?

Your codec 10ec0883 is not natively supported. You'll have to patch the AppleHDA binary. You want to replace a supported codec such as 10ec0885 (alc885,889a).

So open up the AppleHDA binary in AppleHDA.kext/Contents/MacOS with hex edit.

Search for "8508ec10" (byte-flip of "10ec0885") and replace with "8308ec10" (byte-flip of "10ec0883").
There should be 4 instances in the SL kext.

mormegil,

Ahhh...thanks for filling me in, about the codec. Is there nothing else that needs doing, to patch the codec, other than changing the identifier from 10ec0885 to 10ec0883? That seems very simple. I'll give that a shot, though, and see what happens.

EDIT: No luck with the edited codec, either. I think something's wrong with my DSDT.aml, though, since the System Profiler still shows no device information, as in that picture that I uploaded. Do you see anything that I missed?

My kexts aren't really empty, I just left out everything but the Info.plist files, to save space in the upload. I have uploaded my entire AppleHDA.kext file, attached to this post. How do my changes look? I used layout 12, as the guide suggested.

Thanks!

The prob might be with codec address (the leading hex that I asked you to change). One time it works with 3 and next it works with 0. Try this:

Quote:

/* Sample */
"ConfigData",
Buffer (0xA0)
{
/* 0000 */ 0x21, 0x87, 0x1c, 0x40, 0x21, 0x87, 0x1d, 0x90,
/* 0008 */ 0x21, 0x87, 0x1e, 0xA1, 0x21, 0x87, 0x1f, 0x01,
/* 0010 */ 0x21, 0x97, 0x1c, 0x50, 0x21, 0x97, 0x1d, 0x90,
/* 0018 */ 0x21, 0x97, 0x1e, 0xA1, 0x21, 0x97, 0x1f, 0x02,
/* 0020 */ 0x21, 0xa7, 0x1c, 0x60, 0x21, 0xa7, 0x1d, 0x30,
/* 0028 */ 0x21, 0xa7, 0x1e, 0x81, 0x21, 0xa7, 0x1f, 0x01,
/* 0030 */ 0x21, 0xb7, 0x1c, 0x70, 0x21, 0xb7, 0x1d, 0x40,
/* 0038 */ 0x21, 0xb7, 0x1e, 0x21, 0x21, 0xb7, 0x1f, 0x02,
/* 0040 */ 0x21, 0x47, 0x1c, 0x10, 0x21, 0x47, 0x1d, 0x40,
/* 0048 */ 0x21, 0x47, 0x1e, 0x11, 0x21, 0x47, 0x1f, 0x01,
/* 0050 */ 0x21, 0x57, 0x1c, 0x20, 0x21, 0x57, 0x1d, 0x10,
/* 0058 */ 0x21, 0x57, 0x1e, 0x01, 0x21, 0x57, 0x1f, 0x01,
/* 0060 */ 0x21, 0x67, 0x1c, 0x30, 0x21, 0x67, 0x1d, 0x60,
/* 0068 */ 0x21, 0x67, 0x1e, 0x01, 0x21, 0x67, 0x1f, 0x01,
/* 0070 */ 0x21, 0x77, 0x1c, 0x80, 0x21, 0x77, 0x1d, 0x20,
/* 0078 */ 0x21, 0x77, 0x1e, 0x01, 0x21, 0x77, 0x1f, 0x01,
/* 0080 */ 0x21, 0xe7, 0x1c, 0x90, 0x21, 0xe7, 0x1d, 0x61,
/* 0088 */ 0x21, 0xe7, 0x1e, 0x4b, 0x21, 0xe7, 0x1f, 0x01,
/* 0090 */ 0x21, 0xf7, 0x1c, 0xa0, 0x21, 0xf7, 0x1d, 0x01,
/* 0098 */ 0x21, 0xf7, 0x1e, 0xcb, 0x21, 0xf7, 0x1f, 0x01
},

Insert it in your dsdt above "layout-id". It's for my codec (alc888). You'll have to convert your "ConfigData" in plist into it. Just separate them into bytes and add "0x" in front.

Quote:

Example: 21871c40 -> 0x21, 0x87, 0x1c, 0x40

Also

Quote:

Buffer (0xA0)

needs to be changed. Mine has a total of 160 bytes if you count above. So 160 (decimal) = A0 (hex)

Lastly

Quote:

Method (_DSM, 4, NotSerialized)
{
Store (Package (0x08)

Increase the size "0x08" if you're getting compile error.

What this does is hopefully set your codec address in dsdt so it stays fixed. Try codec address 0 thru 3 and report back.

Oh please, lets not make a big deal out of this... You know what you are doing, I dont! I'm just following your lead. I am your dsdt bitch right now

repalced the whole hdef section with what you asked. Does not recompile and produces 47 errors. Here is the log and the dsl file I made, and my "clean" dsdt.dsl

You'll be as famous as fassl and netkas man loool... this is a huge deal with many laptop alc889a !!

it's fine. no errors. only warnings which can be ignored.

Hi m8,

As the guide suggests this is for 889a and even then some people have issues with that codec so for the moment I cannot help you with that.
As for VM I use Parallels 5 in Snow Leopard 64bit running Windows 7 64bit without issues (except maybe Aero interface enabling/disabling whenever it feels liek it)
I have encoded 2 vids with ConvertXtoDVD (the reason I need a VM) and the output was perfect.

I'll take a peek at your file but cannot promise anything (noob at this)

Parallels 5 in Snow Leopard 64bit running Windows 7 64bit
