Thank you very much, I will try this folder. I use a sound card in the motherboard. When the sound disappears, it remains in HDMI.

You should use the hdmi audio or the onboard audio, those work for sure.

Checked the folder. No sound after sleep. HDMI is not convenient to use. I do not have audio speakers in the monitor.

Try this EFI. What is the name of the sound card? screen flow telestream audio?
Hi, could you please take a look at my config as well? I am in the same boat as j1979, FCP crashes when I apply effects.

I see that you've changed the SMBIOS to iMac18,3. Wouldn't it use iGPU for h.264 and HEVC? I want RX580 to handle both.
And yes, speed step is working. Or at least I think so, I use CPUfriend with a merged SSDT. Using just plugin type causes my machine to reboot when waking from sleep.

I have better FCPX speeds with both enabled.
Does FCPX crash with the current settings?
Is the CPU at 0.8 Ghz idle?
