I’m running macOS Catalina 10.15.2 on my Lenovo Ideapad 300-15isk laptop. Everything works, except HDMI audio. I can’t get it right no matter what I try, and I’ve tried every guide I’ve found. I was able to patch AppleHDA.kext and sound is working great, but still no HDMI audio in the sound properties window, only 'internal speaker out'. Here are my specs:
Lenovo Ideapad 300-15isk 80RS Intel core i5 6200U @ 2.40 GHz Intel HD 520 Graphics 16GB of DDR3L RAM @ 1600Mhz 480GB SSD as primary boot and system drive 1TB SATAIII HD as secondary. Backup drive Dual boot (macOS Catalina 10.15.2 and Windows 10 Pro)
Please refer to attached .docx file containing a picture of DPCIManager window and picture of Kexts installed in EFI-EFI-CLOVER-Kexts-Other. Also, in case you wish to look at it, I am posting the link to my RunMe files. Thanks a lot for your time and help!
Hi again... I'm update to Catalina and my old config.plist to patch my laptop with new methods... all work fine. Only I have a little problem with may HDMI connection, when use it my laptop reboots. Please... Can anyone see my problem reporting files and tell me... Thanks in advance.
PD. I've noticed that I also have another problem, my laptop don't go to sleep.
Finally I finished the installation of 10.14.6 on my Dell E5440. Everything works just fine, but HDMI will not work. Every time I plug it in, it causes a grey screen on my laptop monitor. Also on boot up. I attached my EFI Folder, maybe someone can help me. I searched a bit and read something about Azul Framebuffer Kext.
My rig is working great driving a single display from Vega 64 via DisplayPort, but I'm having a devil of a time getting a TV monitor working via HDMI on the same card.
My TV lights up an input icon when I plug it to the Vega (see attached--notice the next port w/ nothing plugged in is grayed out). So I know some electrons are flowing (maybe EDID?), but it never gets a signal. I've tried several HDMI 2.0 cables.
I'm running a vanilla install of 10.14.6, as iMac19,1, with just Lilu (1.3.8) + Whatevergreen (1.3.1). System recognizes the Vega and seems to be correctly using the UHD630 headlessly. I just can't get HDMI out of the dGPU...
I've tried the "-raddvi" and "agdpmod=vit9696" boot args, no dice. I've tried the kext patch workaround for disabling board verification, also no go (not surprising as I think that method is now obsolete for my setup).
I hit the same wall running 10.14.2 as iMac18,3 with a different platform-id before updating.
Here's my whole EFI.
Any assistance at all is hugely appreciated!! Thanks y'all.
