Sound with Intel/ Conexant High Definition Audio?, on Toshiba 17'' Laptop --> AppleHDA.kext fails to load Options

[BugsB]

wow how fantastic, mentorek !! Yes, AppleHDA is unable to load the Conexant HDA Layout-ID property - whatever that exactly means.

Skippy (together with NeoPheus) is working on it, too, as you can see here

Good luck (and keep us posted ) !

@ mac fly: Toshiba uses altering IO and/or memory ranges in its Laptops' chipsets, so the AppleAzalia-solution does not work with the Conexant HDA in Toshiba Laptops.

I have the same on my HP DV1708NR with the same driver & device id's.. My sound is working, but NO MIC or LINE IN support.. Under System Preferences it shows No Input device available..

I've even tried using a USB Mic which is completely independent of the Sound Driver I would think, and that wouldn't take either.. Any clues?

Works. Thanks Skippy : )

Works. Thanks Skippy : )

which kext from which posting did you take, and what's your Hardware (whoch Laptop)?

[MarcCyberWiz]

Also doesnt work with my Toshiba M100, which is a realtek.

CODE

Have you tried to repair permissions on this new kext?
# chown -R root:wheel brand_new.kext
# chmod -R 755 brand_new.kext

Cheers,

Hello BugsBunny and the rest of Conexant HDA users,

After doing loads of different modification of kexts and trying to get this piece of crap to work I'm still with nothing
I've tried all possibilities, even binary hacking of the detection part of kexts with no success.
But... I've done some work under Linux and I've got it (the Conexant chip) to work with acpi enabled. I know that you all want to get it working under OSX but it might be some thing to think about. The answer to get it to work was modyfing DSDT table and loading it when booting kernel (using initramfs). After that I have the sound and acpi working together what makes me happy
BTW. I'm using Toshiba Satellite P100-219.

I don't know if it could be useful for OSX but I'm sure that may explain some problems with our hardware.

Cheers,
Mik

P.S.
Yeah, I know that it isn't Linux forum but I wanted you to know that the problem might have connections with buggy BIOS/DSDT in our machines.

P.S.#2
I've switched to another WLAN card (using ar5006egs chipset) but it isn't working (I get: "kexts loaded unsuccessfully" message when trying to load the Atheros kext). Anybody with working solution?

[BugsB]

Hi mentorek, thanks for your efforts & your report. Nice you got it working under Linux. I never heard of DSDT. My naive idea would be to edit DSDT within Mac OS x86. But probably you have thought about that already, but DSDT cannot be edited here as easy as with Linux I guess ..

Hey BugsBunny,

I didn't really search for DSDT loading in OSX yet, but I think it will need some coding - for example new kext or piece of code with this routine adapted. Maybe it's possible without any coding, I don't know. Will try to investigate it during next days and will inform you about the progress.

Cheers,
Mik

P.S.

Merry Christmas and a Happy New Year!

nice creative installer - but the Azalia approach does not currently work for Toshiba Laptops

perhaps you need applehda solution rather than azalia
skippy still working hard for it

glad to hear it works for you

thanks,
maybe you're right its alter IO and/or memory ranges in its Laptops' chipsets
or just need a correct AppleHDA Conexant HDA Layout-ID property and inject it

[BugsB]

hm yeah I have this huge horse syringe here filled with all sorts of Layout-ID properties - how do I need to inject it now (sub binarane, intra plistular .. )

i believe if there's applehda solution for connexant, it will use same method with realtek,
i dont think without injection into kernel, efi will tell kernel to load it natively,
unfortunatelly alcinject only work with 8.8.1,

[ugriecu]

it work for me too. but any solution for input????
HP pavillion dv5251 audio: conexant hd
bye

[SLml2]

Hi,
it works for me too, the laptop is HP Pavillion dv6111ea using conexant hda (under windows device manager: HDAUDIO\FUNC_01&VEN_14F1&DEV_5045&SUBSYS_103C30BB). Still only output (speakers) and no mic or spdif. Any chances for input at least? Thanks and congatulations on your good work guys
