goodmorning!

It's great to find this topic!

I have a toshiba P100 - 373 PSPA0E, which is not listed in the start post. What bios should i use? I have the Conexant with Vendor-ID 14F1 and Device-ID 5047.

Any help would be appreciated, would love to hear some sound coming from my speakers

Hi RobbeD,

You should download the "Small but complete package" in the first post of BugsB.
And you have to follow the instructions provided in the package.

But you have to know that the sleep fonction should not work and in windows you have "2 new unknown devices". It's not a problem because your Tosh. will work as it should : great.

Hi, friends.

I really don't know what to do and even what to think!!! BUT situation changed again... I installed 4 Gb RAM (2x2) into my Toshi... And after that SOUND COMPLETELY STOP WORKING (BIOS is the same)!!! But Sleep is now functioning in Mac.

With great respect, jazzminos.

Hi, friends. Here is my post. Please look http://forum.insanelymac.com/index.php?sho...mp;#entry949123

I would rather check http://forum.insanelymac.com/index.php?showtopic=132757
This might solve all the issues with buggy DSDT without any recompiling and changes in the BIOS image.

mentorek

P.S.
I'll update you during the weekend 'cause I have to find some free time to experiment.

Hi. Thanks fo reply! Now I need to correct the ONLY one problem - memory & sound. Waiting for Your ideas. Thanks.

Can You tell me what is Chameleon (a version of EFI???) and how to install it? Just in two words...

With great respect, jazzminos.

Chameleon == Boot manager

I'll try to create step-by-step install procedure.

Thanks... Your help will be extremely valuable.

Thanks... Your help will be extremely valuable.

As for now I'm able to use AppleRTC.kext and AppleIntelCPUPowerManagement.kext without any problems (safe updates!).
No changes on the sound field though.

I'll keep you updated 'cause I've got to test a bit.

Cheers,

Hi, Mentorek.

I get VERY sad about my sound...
Can You tell more about AppleRTC.kext and AppleIntelCPUPowerManagement.kext. If it is possible to update Leo safely it is fine.

Thanks.

With great respect, jazzminos.

Hi Jazzminos,

The sound is not working for me. I have some ideas but I'm out of time to check them.

The updates should be safe now. Both of those kexts are loaded and system is working without problems. Only drawback is that the CPU tends to get hotter than without AppleIntelCPUPowerManagement.kext

Cheers,

Do You have any ideas how memory banks affect sound? Why 2x512 work and 2x2Gb does not? Frequency and vendor are the same. What should be corrected?

I didn't understand what You had changed to make AppleRTC.kext and AppleIntelCPUPowerManagement.kext work. It would be very nice for me to make updates safe... Share a secret please

With great respect, jazzminos.

p.s. I wish we had BugsB among us. I suppose that he could help solving problem.

As for memory upgrade: I have no idea. Maybe it's related to the amount of memory 945GM + T2x00 processor can allocate?

I've changed DSDT source and had compiled it back. Of course I had to install patched Chameleon. As for now the only way to use it is to download Chameleon installer, installing it, downloading the zip file from the thread about Chameleon w/ DSDT override and dd'ing boot1h file to the first sector of your OSX partition (this last step is only needed to boot OSX using journaled, case-sensitive UFS+ file system).
After all steps had finished you would have to put your compiled DSDT.aml file on '/' and reboot OSX.

Tonight, I'll have a look at my old DSDT files from Linux maybe I'm missing some parts in the new one that came with my mobo.

This seems not to work for sound issues in my case. Could you please tell me which BIOS version are you guys using to get at least sound-out?

Cheers,
mentorek

[jazzminos]

My sound worked fine with 4.00 BIOS - http://www.mediafire.com/?lez2904py40 . But with 512 memory banks ONLY.

Hi, mentorek. What do You think about this topic - http://forum.insanelymac.com/index.php?showtopic=136531 ? Maybe there is a way to solve problem via AppleHDA? I got a Linux dump for our Conexant chip... AppleHDA Patcher does something but still no sound.

I'm getting closer with Chameleon+DSDT Override + AppleHDA + HDAEnabler. Only problem I have is that I cannot do the Pin Configuration properly. I'll post my findings in an hour or two.

cheers,
mentorek

Edit:
Using method from below and some changes in AppleHDA binary and plists I've achieved this:


It is also showing up with plenty of details in IORegistryExplorer. (I'll provide a screenshot later).

The problem is that I don't know how to set up NodeID's in plists of AppleHDA.kext and also if that would work at all...

Still this is much of a progress. Hopefully I'll find a way to set it up correctly.

[jazzminos]

Thanks for Your efforts, mentorek... I'm sorry that I can't help You otherwise being a tester... I don't know much about programming Waiting for Your reply... Maybe it will be useful to make a new thread and to attach it in the top list of sound drivers forum... I can ask a moderator if we can do this.
