Hi,

I've got some trouble getting my audio out to work.
I'm running ML 10.8.2 with custom DSDT and AppleHDA.kext. Audio input seems to work, at least I get some movement in System Preferences Audio input. Everything regarding audio out shows up, I've got a device in Device Manager, OSD when I push my fn keys to toggle sound. My Notebook recognizes, if I plug in headphones and switches the output device to headphones. Still got some errors though (see attached screenshot "dmesg").
So I dont think, there's much left to be done to get audio out working, but I dont know where to look...
If you need any more information, let me know :-)

I'm also interrested in your problem, i have the same audio chip and i don't really like VoodooHDA. Please let me know how it goes and attach your AppleHDA and HDEF section in DSDT if any improvement.
Thanks!

OK,

got it working. At least internal speakers with autoswitch to headphone. No sound thru HDMI so far with my machine

Device (HDEF)

laptop, lenovo G480. Audio id shows as 8086:1e20
Audio device: Intel Corporation Panther Point High Definition Audio Controller (rev 04)

I'm not sure which codec is 8086:1e20 ? I tried several patched AppleHDA with dsdt fix, not worked. this topic's kext and dsdt,
Sound assertion in AppleHDAController at line 483
:(

But i'm using 10.8.0. Any help or link ? for 10.8.0 and 8086:1e20 which one to use ?

I have tried your kext and it does not work on my laptop. I have the same sound card with the same vendor and device ID

good job hampel, finally i got my Satellite L840 sound working. After finding for a month, finally i got this working, My Graphics and Audio, but the sound only working with -f on kernel flags, so i add -f to org.chameleon.boot.plist kernel flags. Thanks.
