No sound after sleep

[MrJoas97]

For some reason my sound won't wake from sleep. I can still see all my output/input devices but my sound output won't work.

When I searched the web I found I should unload and reload my sound extension so I tried but it did not work. It still had no output.

I tried some patched applehda's I found for my codec but they did not work. They would not give me output even before sleep. Sound input worked fine.

I also tried patching the applehda myself but I failed and it would not work. It did not even show me any output/input devices. I have a IDT 92HD99BXX codec.

 

Can someone help me to find a solution to this problem. 

 

Thanks,

Joas

 

PS: I attached my codec_dump.txt from linux.

 

EDIT: I managed to get patched applehda working but sound after sleep still does not work.

Try CodecCommander https://github.com/Dolnor/EAPD-Codec-Commander

 

Depending on the codec, the hardware amplifier gets shutdown during sleep but OS X fails to power it back on during wake. This kext is meant to ensure the EAPD is turned back on after wake.

I tried using codec commander and I also tried using the EAPDfix.kext but they did not work. kextunloading and loading applehda does not enable the sound either. It  just won't enable until restart. I tried to kextunload/kextload applehda while it has not gone to sleep and it worked. Sound was working after the reload too. But after sleep it does not work. 

 

Could it be possible I did something wrong when patching the AppleHDA.kext?

I attached all the files I used for editing the applehda, the applehda.kext itself and the codeccommander.kext that I used.

I'm no expert, but how did you patch your AppleHDA.kext? Are you using Clover? Make sure that CodecCommander is installed in S/L/E and not Clover's boot folder.

Hello everyone.

Try this way.

System Parameters/Try select Inject System ID 

and unchecked box smbios.

I used this guide for patching the AppleHDA: http://www.projectosx.com/forum/index.php?showtopic=465. I am using clover. CodecCommander is installed in s/l/e. I can see CodecCommander in the console too. It says it's enabling the AppleHDA codec but it does not work.

This did not enable sound after sleep. It did however get rid of a glitch I got before when booting with a hdmi cable attached.

I use to have the same problem, but now I don't.

 

Also, I was playing some time with codeccommander and I remeber I had to change some settings in it (in the github page of codeccommander you can find a readme on how to do it).

 

I use clover with audio id injection and run "audio_cloverALC-100_v1.0.3.command" (google it, as I don't remeber exactly where I got it) wich basically adds a kext to the clover kexts folder and some kext patching.

 

This last thing is what makes my sound work after sleeps.

Thank you for your reply, unfortunately I have a IDT codec and the command only supports Realtek codecs.

I managed to fix it! As it turns out my ssdt was not properly configured. I removed the ssdt after which the laptop failed to sleep or rather just wake up from sleep as soon as it entered sleep mode. I fixed that problem by adding the boot flag -gux_defer_usb2.  Now CodecCommander was able to wake the audio from sleep.
