aldoemilio Posted October 24, 2012 Share Posted October 24, 2012 Hi, I will appreciate help on this issue. I built a system based on a GA-Z68A-D3H-B3 (rev 11) MB and an Intel i7 2700K Processor with 8 GB RAM Installed Snow Leopard following instructions I'd found on tonymacx86 blog, and ran MuliBeast. I can´t get the sound to work, the system profiler shows the audio card, but system preferences "No Output Device Found". This is what System Profiler output: Intel High Definition Audio: Audio ID: 892 S/PDIF Optical Digital Audio Output: Connection: Internal Line Output: Connection: 1/8-Inch Jack External Microphone / iPhone Headset: Connection: 1/8-Inch Jack External Microphone / iPhone Headset: Connection: 1/8-Inch Jack Headphone: Connection: 1/8-Inch Jack S/PDIF Optical Digital Audio Output: Connection: Optical I connected a Sony stereo system in the rear output jack and restarted several times with same results. After reading other posts I downloaded IOreg and ran it, a zipped report is attached Aldo’s Mac Pro.ioreg.zip Thanks in advance for any help or suggestions!

aldoemilio Posted October 24, 2012 Author Share Posted October 24, 2012 Well, after some research I solved the issue. I found a post in an external forum where a moderator asked to the guy having a similar issue, if he had deleted all the HDA items in System/Library/Extensions (after doing some installations) I went to S/L/E and (first) found 2 DSDT files, (I installed both) so I deleted the wrong one, and trashed all the HDA folders, then restarted, and voilá, the sound is working perfectly. I hope this can help anyone with a similar issue. Link to comment Share on other sites More sharing options...
