[Help] AppleALC Kernel Panic after Catalina update

[Taeyon]

I've got the same problem. As noted above, if I remove the AppleALC kext, the system does no longer reboot when waking up from sleep. But I have no sound... My AppleALC is of 1.4.2 (latest).

As tried an older version 1.3.9 of AppleALC, it has the same problem...

Same for me, and update from Mojave 10.14.6.

Back to voodooHDA.

I'm searching in AppleALC's code and I may have found something, I'll keep you updated. If someone else with programming skills wants to help, it would be appreciated: I'm looking at kern_alc both header and cpp files, it seems to be the right way to go, since it check for HDAU and uses IOServices (remember the panic at IOServicePMM?).

Another really helpful thing would be having your log of appleALC but you need to install the debug version and start with -alcdbg

I've finally checked the debug of AppleALC that i'm attaching:

I've pinned where the pc crashed and where it woke up normally because of a dp cable attached

I also had this problem in Catalina. It looks like I've managed to fix it by changing one line in my config.plist. Here's a part of my "Devices" key in config.plist. I had "<integer>11</integer>", changed it to <string>NO</string> and no more reboots after wake!

<key>Audio</key>
<dict>
<key>AFGLowPowerState</key>
<true/>
<key>Inject</key>
<string>NO</string>
<key>ResetHDA</key>
<true/>
</dict>
