Use Search, Q upper right of every page.

Toleda- if there is an actual fix for "no audio after sleep/wake"- can you please provide which search terms because every thread I've found is either questions w/ no answer, or people suggesting to use a script to disable/re-enable the audio kext. If that is indeed the "fix", so be it, but if there's a better way- I sure as heck haven't found it whether using google to search the site, or the search that's built-in to the site. Thanks,

1. I just installed OS X Mavericks on my new hackintosh using the Clover Bootloader, but I don't have any audio still. I've only tested it with headphones and there is no audio and no outputs when I check System Preferences>Sound options. I've tried using the clover patch, but still no sound... I'm not sure where to go from here.

Hi toleda. I edited a new one and made node 21-23 as line-outs, node 20 and node 27 grouped(node 20 as line-out, node 27 as HP-out) but 3 sound assertions show up. The node 20 and 27 still low sound. I don`t know where to fix now. Please help me.

Sound assertions shows below.

Sound assertion in AppleHDAEngine at line 10177

Should I add 01471C02 01B70C02 in the end of configdata?

01471C10 01471D40 01471E01 01471F01 01571C20 01571D10 01571E01 01571F01 01671C30 01671D10 01671E01 01671F01 01771C40 01771D10 01771E01 01771F01 01871C50 01871D10 01871EA0 01871F90 01971C60 01971D90 01971E81 01971F02 01A71C70 01A71D10 01A71E81 01A71F01 01B71C80 01B71D40 01B71E21 01B71F02 01E71C90 01E71D10 01E71E45 01E71F01 01471C02 01B70C02

P.S
I got the low volume problem solved by adding two codecverbs. Now the annoying sound assertions need be get rid of.
Below is my AppleHDA, all work as normal but 3 sound assertions need be fixed.

I've tried using the clover patch, but still no sound...!

Missed a step. See toleda/audio_CloverALC/README:
2. Clover/config.plist

2. EFI/Clover/config.plist/Add​

2. KernelAndKextPatches/KextsToPatch​

1. AppleHDA/ALCxxx binary​

1. Select patch for installed codec​

2. AppleHDA/Resources/xml>zml​

Outstanding! With your permission and credit, I'd like to post test a test AppleHDA.kext for verification of the fix. OK?

 

[kidalive]

ok, let us do it.

Thanks a lot Toleda! I did the patch over again, following the instructions to a "T" and the audio finally works!

toleda, I got rid of 3 sound assertions by pathing the binary of applehdacontroler. Dunno if this is a right fix. But no error show up.
I have a question. I got all line-outs working but for 7.1 surround sound, should I modify the amp of pathmap? A Chinese said apple use IntSpeaker to make 4.1 or 6.1 multichannel working, he has not mentioned 7.1. I noticed some stock AppleHDA us different bind and channel number. Any idea? I think you should do some research and tests of this.
