Rumfy Posted January 29, 2014 Share Posted January 29, 2014 Hi all I succeeded in installing Mavericks with the Niresh distro. I have 2 problems: 1. Multiple desktop setup is not working (Sapphire Radeon 6870), Mac does recognise my second display but nothing is showing on the second monitor. 2. I got very choppy sound, my sound card specification: VIA VT1818 8-Channel High Definition Audio CODEC. I was hoping that some one could help me out on this one. Any help/comment is appreciated, thanks! Link to comment Share on other sites More sharing options...
tragediana150 Posted January 29, 2014 Share Posted January 29, 2014 (edited) Try VoodooHDA.kext to your problematic sound. How you connected your dual displays? DVI, VGA, HDMI? Try to connect first to the HDMI and second to DVI port (VGA is too old, and this making some problems). Also try to change resolution on your second (not working - black display) monitor using SwitchResX.app Good Luck Edited January 29, 2014 by tragediana150 Link to comment Share on other sites More sharing options...

I can try your solution and connect 1 by HDMI. I will give you feedback after I ran the tests. Link to comment Share on other sites More sharing options...
Rumfy Posted January 30, 2014 Author Share Posted January 30, 2014 Thanks Tragediana, I can confirm that the sound is now working flawless with the VooDooHDA kext and my second display is also working. I do now have 1 last problem: My youtube video and sound is not in sync and the mouse is stuttering every now and then. I guess it will have something to do with the graphics? Does anyone has an idea? I also took a screenshot of my system information: graphics Link to comment Share on other sites More sharing options...
tragediana150 Posted January 30, 2014 Share Posted January 30, 2014 Hmm...strange problem Maybe try VoodooTSCSyncAMD.kext? I don't know if it is problem with the graphics, but you can try this kext to your processor Link to comment Share on other sites More sharing options...
Rumfy Posted February 3, 2014 Author Share Posted February 3, 2014 Hey Tragediana I did some extra research at home. I fixed the mouse movement problem by booting with GraphicsEnabler=No. Now I only have this problem when watching movies. The sound is not in sync with the movie. Any other suggestions then VoodooTSCSyncAMD? I installed the kext, repaired permissions and rebooted, but the problem still exists... Thanks a lot already so far !!
