to fix audio become distorted, you need to add EAPD and Pin Widget Control signal to ConfigData and WakeConfigData (you can try this https://github.com/lolipuru/Thinkpad-T480-Opencore/commit/4981a8d11ad0fea6045578353d62514bf7f637de it should works)

AirportItlwm doesn't support on sequoia yet, and not anytime soon
edit: seem like AirportItlwm can works with OCLP but you need to "fake it" to broadcom wifi card
Hello. Firstly, thank you for the work you are doing and for making EFIs available. I tested your EFI versions for the recently released Sequoia. They work except for small details... I would like to know more specifically what Wifi/Bluetooth card your Thinkpad T480 uses. Mine is similar to yours, but it uses an Intel AC8265 (WiFi/Bluetooth) and Intel I219-LM board (Ethernet). In addition to a Realtek ALC257 audio card. But I need to use the version with "AirportItlmw" support, because I need to log into a WPA2 Enterprise WiFi network. That is, I cannot use the version with Heliport because I lose this functionality, which is necessary for me. Furthermore, I noticed that after the notebook goes into sleep mode, the audio comes back distorted (low volume, with a kind of reverberation, "echo"). Going into settings and making some audio adjustments sometimes fixes the problem (a slight inconvenience). But the main problem is with the Intel WiFi card. I have been searching on the internet for ways to activate "AirportItlwm" with an Intel card (in my case AC8265) using Sonoma >= 14.4 or Sequoia 15.0, but I am not having success. I appreciate tips/suggestions to try to overcome this problem.
