Hi @Baio77, @Hervé I have an updade for this issue. I remove the Layout id in device propieties and modifify the boot parameter to test. layout 11 speakers and external mic works, layout 18 only speakers works layout 86, speakers and external mic works layout 96 nothing works, layout 97, only speakers works layout 99, nothing works layout 100 only speakers works Internal mic not works for whatever layout id that I used. Reviwing the documentation, maybe the root cause is, because the lenovo T14 have implemented the intel SST technology. Other forums talk about this issue with Hackintoshes, in Lenovo laptops. Dortania guide said the same. https://dortania.github.io/OpenCore-Install-Guide/macos-limits.html#miscellaneous Other post for the same audio chip and intel SST https://www.installhackintosh.com/installed-hackintosh-system/1213-success-hackintosh-macos-monterey-12-2-1-build-21d62-in-lenovo-ideapad-gaming-3-15imh05 Any one hear about a workaround for this? Thanks for your time and support. Regards Victor

Hi The EFi is located in the guide linked in my first post Victor

Hi @Baio77 Sorry. Here is the file: Victor’s MacBook Air.ioreg Hello @Hervé I execute your recommendation, I remove the layout-id by hand using vi editor into the config.plist file. I make an screenshot that opencore configurator see the new config entry: I try to modify the -alcid=xxx parameter with otherones whithout success. 86 and 96 values activate the audio, speakers works, but no mic. Thanks Regards Victor

Hi Baio77 Thanks for your help and time. Regards Victor

Hi all First, thanks for all the effort. I have a Lenovo T14 with macOS Monterey 12,4 working fine. I used this guide: I try changing the alcid=xxx in boot args with Propertree to other ones that are showing in AppleALC wiki, but, same result, no MIC. From wiki Realtek ALC257: 0x100001, layout 11, 18, 86, 96, 97, 99, 100. 86 is configured in config.plist Maybe, i make something wrong. Im new on this, any help will be appreciated. Thanks Victor S
