hampel Posted February 10, 2013 Share Posted February 10, 2013 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 :-) Link to comment Share on other sites More sharing options...
slayer2333 Posted February 10, 2013 Share Posted February 10, 2013 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! Link to comment Share on other sites More sharing options...

sarim khan Posted March 10, 2013 Share Posted March 10, 2013 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 ? Link to comment Share on other sites More sharing options...

Mochrira Posted January 1, 2014 Share Posted January 1, 2014 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.
