remenic Posted September 1, 2012 Share Posted September 1, 2012 Hi there, I've managed to install Mountain Lion on my ASRock H55M Pro, a pretty smooth experience using this guide. One thing that doesn't work as smoothly is sound. I've installed VoodooHDA and it shows up two output devices (analog and HDMI) and one input. Ideally, I'd like to get sound over the optical out interface, which seems to happen when I select HDMI. Unfortunately, the sound is very distorted. Listening closely, I can hear some of the actual sound through the noise, so it's doing something at least a little bit right. I've tried setting the Format via the Audio MIDI Setup, and while it makes some difference, the result is always heavily distorted. A Google search revealed a bunch of things, like setting some parameters in the VoodooHDA.kext's Info.plist, but everything I've tried thus far did not improve the situation. Nor made it worse, for that matter. If anyone could give me some pointers, I'd be happy to try them. Link to comment Share on other sites More sharing options...
remenic Posted September 2, 2012 Author Share Posted September 2, 2012 I've managed to fix it by installing VoodooHDA 2.7.4 from http://www.osx86.net/view/2746-voodoohda_2.7.4_pkg_installer.html. This release isn't on the official VoodooHDA site, so I missed it. Link to comment Share on other sites More sharing options...
