Lenovo Y50-70: no sound after upgrading from Sierra to Mojave

[c20h28o2]

Hello, dear community!

I have a laptop Lenovo Y50-70 and some time ago successfully installed Sierra (not High), seems to be, using this guide:
https://www.tonymacx86.com/threads/guide-lenovo-y50-uhd-or-1080p-using-clover-uefi.232960/

Everything was working fine, I changed Wi-Fi to broadcom's one. I think sound was working fine natively, because I'm pretty sure that I didn't use VoodooHDA.kext. But now, I upgraded to Mojave (not beta) and completely lost sound. There is no sound device, no input in sound settings. Everything is fine, just except sound.

Everything I did is upgrade to Mojave, after that updated Clover, placed required kexts in "Other" folder - same as it was for Sierra, and placed same config.plist which, again, was used when Sierra.

I'm sorry that I do not provide any additional info. I just would like to ask, where should I start first, because I'm really afraid to crash my Mojave while trying to solve this problem.

Thank you!

Not a guide. Moved to laptop support.

Make sure you follow all post install instructions here:
https://www.tonymacx86.com/threads/guide-lenovo-y50-uhd-or-1080p-using-clover-uefi.232960/

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.

Use the gen_debug.sh tool mentioned in the FAQ, that way it is less likely you'll omit something.

Solved The problem was in EFI partition name, which was (I don't know why) "NO NAME" - yep, with space And install_downlods.sh script didn't work correctly because of that space)) So, I renamed partition and everything is fine now

Thank you for all your work, all your repositories and scripts!

Yeah, I should probably review all scripts for "spaces in paths" problems. But if you followed the Y50 guide from start to finish, your EFI would be named "EFI"...

I think you need AppleALC since the old AppleHDA patch doesn't work ever since Apple removed several audio layouts in mojave
