mikewithpaws Posted July 29, 2012 Share Posted July 29, 2012 I know this may seem like an obtuse place to put this- but since the sound is coming through the HDMI, and thus through the graphics card, I'm a bit stumped. To make matters weirder, I am unable to watch video files on my computer unless I install the voodoohda .2.56 or .2.61 kexts- though they don't allow me to hear anything, either. I've looked everywhere for an answer to this so I thought I would try here. System: 750 gb hdd 8 gb ram core i3 ati 5450 hd I should mention that I have onboard audio and a soundblaster audigy card on the board but neither of these are being detected either so I am focusing on the HDMI as this would be my preferred means. When OSX first loads it recognizes the graphics card right away, though since I was convinced this was an issue of the graphics card I tried changing it to the 5400 instead of the 5450 series with no change at all. Please help as I'm totally confused. Link to comment https://www.insanelymac.com/forum/topic/281169-ati-5450-w-mountain-lion-no-sound-through-hdmi/ Share on other sites More sharing options...

indiandragon Posted August 14, 2012 Share Posted August 14, 2012 i have the same card , but how you get qe/ci working? i can watch video with audio but cannot get qe/ci All you have to do to get the QE/CI and Dual Video through HDMI/DVI is to add your device id to the info.plist of ATI5000Controller.kext,ATIRadeonX3000.kext . 1. They are found in /System/Library/Extensions 2. Take them to desktop,right click->show package contents -> edit info.plist -> add your device id to <key>IOPCIMatch</key> 3. Install the kexts using kext utility. Test the video, use dvd player and chess. If you have grained screen or no dual monitor , Boot with: AtiConfig=Shrike for VGA, HDMI for some pc. AtiConfig=Eulemur for LVDS (internal display) for some pc. AtiConfig=Hoolock for VGA, LVDS mirror for some pc.
