Working for me without fakepciid. Lenovo IdeaPad S340 with Ice Lake i5-1035G1 and Audio Codec ALC257(alcid=11)

The old patches should be just replaced with this new one, which is confirmed working on ICL platforms. I wonder if this patch could become the default one for Intel HDA since Sunrise Point (8086:9d70)?

Actually quite possible. Because it makes little sense to use them together. We will need external testing though, because nobody here has Ice Lake.

Sounds good to me. @m0d16l14n1, @Ardentwheel, @xenonstride this build only includes the new patch and eliminates the old ones. Please test.

@fewtarius the build seems to be working, nothing changed

working for me too

Works on my Inspiron 7793 preceding ALC didn't gives me any sound but made my processor running hot (75/80), now with layout 13, I get sound on HP,no headphones and a reasonable temperature (55/60), thanks

Audio works on my Acer SF313-52, but I found that if I plug in HDMI cable(from type-c),my notebook got a black screen and reboot, the old version(without this patch) doesn't have this problem.Is it possible for this patch to cause this problem?
Sorry for my poor English.

0x06C8、0x02C8、0x34C8 HDaudio controller
HDMIAudio no work！！
音频控制器ID为0x06C8、0x02C8、0x34C8的DP/HDMI音频不正常，识别不到没声音
问题应该是出在
find：0E0000BE020000004889DF
Replace：0E0000B8709D0000EB0690
我的解决办法是仿冒0xA3F0，之后全部正常！

你好，我想请教一下怎么仿冒0xA3F0，大概步骤是什么样的？谢谢！

I think I have this problem too, when I plug the DP/HDMI cable, the system will crash with this error log.

I tried to spoof these device ids by this there methods:

1. modify this icelake patch in the Controllers.plist in the code of AppleALC, find 0E0000BE020000004889DF and replace 0E0000B8XXXX0000EB0690, XXXX means C89D, or F0A3, then rebuilt and put it into EFI
2. add device-id property with the value C89D0000, or F0A30000 into the opencore DeviceProperties.
3. with both 1&2 and the same device-id

All of them failed, the speaker icon is greyed and can not find the sound device with all of these combos.

spoof 9d70 and 9d71 with method 1 have sound but will crash when plugin the DP/HDMI cable

34c8 is the default value of ice lake cpu if I don't modify the device id with method 2.

I did some tests, this patch can have some modifications (for some specific device), maybe this will be useful to someone.
