Crabhunter Posted February 13, 2013 Share Posted February 13, 2013 Hi, I'm working on a new laptop and I'm currently working on getting sound. The laptop has an intel hm77 chipset and intel high definition audio. I have tried all the voodoo kexts I can find and at best just get a crackling when a sound is played and at worst an unbootable system. Any ideas where I go from here?

WaldMeister Posted February 13, 2013 Share Posted February 13, 2013 Find out which sound chip you have. You probably need a patched AppleHDA and a DSDT edit to get sound working. The easiest way would be extracting your codec from an Ubuntu Live usb. How to do this is described in the following post: http://www.insanelymac.com/forum/topic/283754-patched-applehdakext-for-codecs-idt-92hd81b1x5-idt-92hd91bxx/?do=findComment&comment=1861876 All information regarding your audio can be found in codec.txt file.

Crabhunter Posted February 13, 2013 Author Share Posted February 13, 2013 I just don't have that much time on my hands to work through that but thanks, it might be I have to.

eep357 Posted February 13, 2013 Share Posted February 13, 2013 Or with IOregestryExplorer: Unless it needs to be sorta working for this part to show up. 1 Link to comment https://www.insanelymac.com/forum/topic/286337-intel-high-definition-audio/#findComment-1888451 Share on other sites More sharing options...
Crabhunter Posted February 13, 2013 Author Share Posted February 13, 2013 I've been to the acer website and I notice the driver they list for sound is realtek, I'm going to install that in windows and see if I can get any clues as to what I might need for osx i.e. alc 889.

Crabhunter Posted February 13, 2013 Author Share Posted February 13, 2013 Well no clues using ioregexplorer, I will just keep trying realtec kexts until hopefully one works. Mike hmm getting bored with randomly trying alc**** kexts, how can I tell in windows which it is, I can't find any clues in the device manager or by looking at the driver files.

eep357 Posted February 13, 2013 Share Posted February 13, 2013 I don't really use Windows. IORegistryExplorer is a Hackintosher's best friend, so chances are you'll need to use it many times. Just launch it, and scroll down to the section that matches the picture.

Crabhunter Posted February 13, 2013 Author Share Posted February 13, 2013 OK that helped, I'm now looking for 269. Sorry I thought it was just a general screenshot I didn't realise how helpful you were being. Very grateful.

WaldMeister Posted February 13, 2013 Share Posted February 13, 2013 Needs a DSDT edit though: http://www.insanelym...-inspiron-1464/ If you don't have a DSDT yet, here's a video explaining how to extract it from windows: http://www.youtube.com/watch?v=wK8sHsQ-76Q It will need patching, you can use DSDT Editor to do so, if you have trouble with it, leave the extracted DSDT here Link to comment https://www.insanelymac.com/forum/topic/286337-intel-high-definition-audio/#findComment-1888636 Share on other sites More sharing options...
