Baio77

From Linux extract Dump with headphone jack inserted or not, if you have an external microphone in case a Linux dump even with external mic connected. I'm just trying to help you and understand how this kext works.

https://github.com/Baio1977/AppleALC/actions alc test for X1 Tablet 3° gen . I created this layout by taking the layout69.xml of the alc 236 codec, I adapted it to the 295 codec and tested it, as if by magic the external microphone and headphones work and feel great. I lost the internal speakers but copy paste from layout77.xml codec 295 and as if by magic everything works. The quality of the integrated speakers is not of good quality but in my opinion it can be improved. My internal MIC is broken and doesn't work in any Linux/Windows OS. Try the kext compiled from github and see if everything works and close the request. Thank you

Unfortunately I no longer have this PC in my hands. I generated new ACPI files for compatibility with the new Bios, but Ventura and Sonoma I was unable to install them for users I followed. I hope to get this PC back soon so I can fix this problem.

https://github.com/Baio1977/DELL-Inspiron-5584 use this patch for I2C . Add SSDT I2C speed

My WI-FI is Intel, so I have no problems with Sonoma

To switch to Sonoma I recommend SMBios Macbookair 8.1 for Skylake, Kabylake and Kabylake Refresh, the HW gen is practically identical for these series and therefore the use of this SMBios guarantees the best functioning...... MacbookPro 15.x would be a stretch as it has a Coffelake CPU AAPL,ig-platform-id Data 0000C087 or 0500C087 device-id Data C0870000

RP01 here your TB3 is connected, but reading ioreg there is some problem it is not loaded. I need to know the bios options for TB3. Alternatively there is an Opencore driver that perhaps activates the TB. https://drive.google.com/drive/folders/19s1mYWFOzf8wlP5kqo4Yaz89z892Ievl?usp=drive_link Test this EFI if start new ioreg

https://drive.google.com/drive/folders/1dcUaouWgueD6xiKFtqkUkKtf1UOJRyZu?usp=drive_link Test this EFI if start new Ioreg I fixed the EFI in general, it was already good, it should be missing the TB3 that you should activate in the Bios. We'll fix TB3 last thing.

Post Ioreg + EFI + DSDT Origin ...

https://drive.google.com/drive/folders/1bttb_aHUCHJb7_asDMIMQuL4l3P7kFBQ?usp=sharing If start ioreg my EFI . I looked for info , I guess you are talking about your Dell Precision 7550 , test the EFI I passed you , updated OC 0.9.2 + kext , I modified some SSDT , see I2C and I added others respecting the SMBios used (MacbookPro 16.4 the most suitable , see CPU characteristics , https://www.intel.it/content/www/it/it/products/sku/201897/intel-core-i710850h-processor-12m-cache-up-to-5-10-ghz/specifications.html )

Add this SSDT in EFI\OC\ACPI and in Config.plist , if start ioreg https://drive.google.com/file/d/116EfXwrSwXHcqpmLxXcbyEUzkx4m9jWz/view?usp=share_link

yes analyzing ioreg I have not observed carefully , but the problem is what you wrote. it is very probable that 2 identical PCs have different HW components and/or different ACPI so it is easy to deal with problems similar to yours. All is well, that ends well
