delete IntelGraphicsFixup.kext

try the attached config.plist

also you have the choice of these id's:
3, 11, 13, 21, 22, 28, 29, 30, 32, 47, 66, 72, 99

you will have to try them one at a time

Thanks for help.

have you done an audio codec dump to see the actual codec?

have you done an audio codec dump to see the actual codec?

I dont know how to do it.
I have changed hard disk. Installed windows 10 again and I see this:
Microsoft GSM 6.10
IMA CODEC ADPCM
CCITT G7.11
Fraunhofer IIS MPEG Layer-3 Codec

have you done an audio codec dump to see the actual codec?

Extracting Linux - Dump Starting from the Linux LiveCD drive (for example Ubuntu, Parted Magic ....) go to the folder / proc / asound / card0 / card # 0 or card # 2 this is a text file of the Linux dump.
or in terminal

cat /proc/asound/card0/codec#0 > ~/Desktop/codec_dump.txt (or) cat /proc/asound/card0/codec#1 > ~/Desktop/codec_dump.txt (or) cat /proc/asound/card0/codec#2 > ~/Desktop/codec_dump.txt


This is what I have to do for identify codec?
