Dudes!

Just found out more relevant info.

Check this out...

patched with address 3, no verbose message, system profiler looses ports.

patched with address 2, assertion "0" errors in boot, sys profiler shows 1 digital port

Then I saw that the plist mormegil provided had different icons. One is plain white, the other has image. I open the ones that have image with text edit, select save as, name in info.plist and UNCHECK the box that says "If no extension is provided name .txt"

Now this makes a blanc icon plist. I checked, and before it was not .txt, but icon different.

Re-patch address 3 plists, repair, reboot, first boot KP with AppleHDA dependancies, second boot assertion "0", no sound but system profiler does show all ports! This is the first non-vanilla kext that does this! Well done.

Still no sound, but one step closer!!

Since you're on a lappy, the only way to properly write your own plists is to create your own codec dump in linux or find one on the internet. Try searching acer laptop forums for example.

The thing is, all the codec dumps we've been using are those for desktop models. Which means 4 analog outs, 2 analog ins at the back and possibly digital ins/outs too. Plus internal ports for connecting to the front connector. Your laptop definitely do not have all these ports and so your layout/pathmaps might be different. So which set is showing all ports correctly in Sys Prof?

What if a port shares 2 connection?

I'll look for my codec dump.

UPDATE: I found this, possible codec dump. The susbsytem is 0x10250146 which maches what my system profiler Device ID number.

its for the same chip, and from a close acer model to mine. Is this the sort of thing you need? never seen a codec dump before. I'll keep searching for my exact dump, it must be around.

Tried posting code, too long. here is the link.

Ok, I think this might do it.

A codec dump for acer 6920g -
00:1b.0 0403: 8086:284b (rev 03)

and has the same DeviceID / sybsystem as me.

Mormegil, up for some more of your black magic?

And if you show me how, I'll be glad to take it from there... but this one HAS to work damn it ! The specs are almost identical to my model !!

If you're certain it matches yours, just go through King's guide. He'll guide you step by step. You will understand things more clearly by reading it.

forgot to upload dump...

I'm at work now, so I'll only be able to try later on.

Ahh! You have a true 889 codec as opposed to the fake 889 (renamed 885). All the above plists are useless for you then. Also, your pinconfig are different as I expected and you might have to hex edit your binary.

Gurruwiwi · #68 09-04-2009, 08:47 PM

So... what should I attempt next?

mormegil · #69 09-04-2009, 08:56 PM

Try this out

SL 1.7.4 AppleHDA.kext for acer 6920g alc889:

Back to no Audio devices listed.

So far, only vanilla AppleHDA and patched with the first two plist you did for Snow (which I guess are the one he updated the first post with) wake up the ports...

isnt this just frustrating
