Dusan Stanimirovic Posted April 29, 2016 Share Posted April 29, 2016 Hello,I have successfully installed OS X El Capitan (10.11.4) from AppStore today.I am using Clover bootloader. After installation, video was working OOB, ethernet after installing kext, but I cannot get audio working.My MB has Realtek ALC662 codec (Intel High Definition Audio)At first time, I tried to use VoodooHDA 2.8.8, but as all versions before, sound is skipping every second. (Listen to VoodooHDA-lag.mp3 ... Recorded sound from speakers with iPad)I tried to change settings in VoodooHDA pref panel, (check, uncheck "Use SSE2"), changing audio frequency in "Audio/MIDI setup" (between 44100, 48000 and 96000), but nothing changes.I also tried to patch nodes, to get all ports. I got all 3 of them, and got sound on all speakers, but like before, it is skipping.As a last resort, I changed IOClassMatch to IOPCIMatch, and typed my deviceID (0x0f048086) in VoodooHDA Info.plist. My card got recognized as before, but problem with audio skipping still persists. After that, I tried to use Native AppleHDA with Clover option "KextsToPatch" I found somewhere on net.I applied this patches: - Patch against assertions (Find: U291bmQgYXNzZXJ0aW9uIA == , Replace: AAAAAAAAAAAAAAAAAAAAAA == )- ALC662-Fix (Find: hBnUEQ == , Replace: YgbsEA == )- Zeroing 10ec0885 codec (Find: hQjsEA== , Replace: AAAAAA==)- Zeroing 11d41983 codec (Find: gxnUEQ , Replace: AAAAAA)After applying these patches, instead of 6, I got no more "Sound assertion in ..." errors at verbose boot), and got 2 of total 3 ports recognized in "System Report -> Audio" (see screenshot Audio.tiff) but I got no Output and Input devices in "System Preferences->Sound" (see screenshot Audio2.tiff).Of course, there is NO sound.In Clover I tried to set "Inject" to layout 0, 1, 2, 3, 5, 12 and 662. But none of them works, and I always get same situation.What am I doing wrong? Link to comment Share on other sites More sharing options...
Dusan Stanimirovic Posted May 5, 2016 Author Share Posted May 5, 2016 Apparently, VoodooHDA lagged, because Clover detected incorrect Bus Speed.Instead of 83000 KHz, I set it to 65970 KHz, and now it is working perfectly Link to comment Share on other sites More sharing options...
