toomanyairmiles Posted May 3, 2014 Share Posted May 3, 2014 Hi everyone, This is my first hackintosh so forgive me if any of these are obvious or known issues. Each time my machine resumes from system sleep the audio goes dead, the only thing that fixes it is a complete restart. I'm on the current version of the Chimera bootloader, have the latest ALC892 kexts, and have tried a complete reinstallation to no avail. For reference my system spec is: Core i7 2600k, Sabretooth P67 (BIOS 2103 & ALC892 codecs), 16Gb RAM, 120Gb Corsair Force GT SSD, 7TB Storage, Twin nVidia 9800 GTX+ OC (non SLI) driving 1 x 26" + 2 x 22" monitors, OSX Mavericks.

Documented 10.9.2 AppleHDA.kext problem. Install 10.9.1 892 AppleHDA.kext.

RehabMan Posted May 3, 2014 Share Posted May 3, 2014 Documented 10.9.2 AppleHDA.kext problem. Install 10.9.1 892 AppleHDA.kext. Strange. Does this only happen with certain boards? I use 10.9.2 AppleHDA.kext patched for ALC892 on my desktop. No problem on resume from sleep. I patch AppleHDA.kext myself. Using your Platforms.xml.zlib/layout*.xml.zlib files, edits to AppleHDAHardwareConfigDriver.kext/Contents/Info.plist and bcc9's v3.0 script for patching AppleHDA.kext/Contents/MacOS/AppleHDA.

toleda Posted May 3, 2014 Share Posted May 3, 2014 Strange. Does this only happen with certain boards? Yes, often 892. I have no issues with 10.9.2 wake on any codec I have. TimeWalker75: "2.6.0f1 introduced extensive power management for Audio Engines. There's now a procedure startPowerManagementTimerForEngine which handles subroutines called StopEngineAtPositionInput and StopEngineAtPositionOutput which previously weren't separate in the binary, on the contrary - it was a single short subroutine, which in 2.6.0 was split and heavily re-coded to help fix audio loss issues after sleep on certain Mac computers.. after 10.9.2 people still complain about audio loss after sleep with some Macs, so we are affected here as well." 1 Link to comment https://www.insanelymac.com/forum/topic/297816-audio-fails-on-system-resume/#findComment-2017099 Share on other sites More sharing options...

Thanks for the info. We're just lucky, I guess.
