gavbrown Posted February 14, 2010 Share Posted February 14, 2010 Hi guys; I'm in the process of trying to get Audio to work on under Snow Leopard 10.6.2 on my Gigabyte GA-EP35-DS3L board. Everything was working fine under 10.5, it was also working under 10.6.0, but since the upgrade to 10.6.2 I just can't get it to work! I've been at this for days and tried various dsdt changes along with relevant LegacyHDA.kext's to no avail. Here's details of the last thing I've tried: ALC888 Installer Changes from: http://www.insanelymac.com/forum/index.php?showtopic=184367 I looked through the ruby code from the "ALC888 Installer project" on that post and extracted the changes it would make to the DSDT and added updated mine with them. I also took the LegacyHDA.kext from there. Here's the MD5 of the Info.plist from LegacyHDA.kext and it's attached below: HD5 (LegacyHDA.kext/Contents/Info.plist) = e51c647cf15f98540211598274558600 Appart from sound everything else seems to be working great. Any help anyone could provide would be greatly appreciated. I'm quite happy to go hacking my DSDT and trying random kext, I've done it enough over the last few days! Cheers Gavin Update: Here's a couple of errors I've got in my kernel log, not sure if they are relevant?

oldnapalm Posted February 14, 2010 Share Posted February 14, 2010 Have you tried removing BuiltInHDA key from LegacyHDA Info.plist? LegacyHDA.kext.zip Link to comment Share on other sites More sharing options...
gavbrown Posted February 14, 2010 Author Share Posted February 14, 2010 Have you tried removing BuiltInHDA key from LegacyHDA Info.plist? LegacyHDA.kext.zip I hadn't, thanks for the suggestion, unfortunately still no audio. Titain made a similar suggestion here http://www.insanelymac.com/forum/index.php...t&p=1410292 but his kext didn't work either Link to comment Share on other sites More sharing options...
