No Audio Devices - AppleHDA Realtek Audio

Yes, looking at that now, thank you.

I would still look at installing an earlier version of the bootloader from sourceforge Link

Terminal: diskutil list
Included in your Problem Reporting folder, Post #830.

Your previous note said Likely the wrong EFI was mounted. How can I ensure the correct EFI is mounted? diskutil list shows one in each of disk0/s1, disk2/s1, & disk3/s1.

No idea. Issue with 4497 was no audio, fixed in 4509.

UPDATE! sound is gone again!

If you use terminal to run the command diskutil list your output should show which disk is the one with your boot volume (On APFS it is actually called out as what the EFI disk is as Physical Store diskx1x2) The output for your should show something similar to the screenshot attached. In my case, on this boot, the correct EFI disk to mount is disk1s1 as I am on APFS. Note: My boot disk changes sometimes every restart so I check diskutil list each time I want to mount and tinker with my config.plist

Edit: Please excuse my AFPS typing dyslexia it's supposed to be APFS

@toleda,

I used Kextbeast and installed FakePCIID.kext and FakePCIID_Intel_HDMI_Audio.kext into L/E. Verified that those files are really there, and restarted. Still, no output device found, and still System Report/Audio shows a blank window.

Change output divice to green rear (using audio cable)

Your screenshot of the Sound Output shows Headphones (Green Front) as the selected audio device.

thanks, that's the wrong one, the sound icon should be black everytime the pc turned on, but intead it's always gray with no option to choose, have to mount EFI Mount v3 and restart system again to get audio working, sometimes need to do a few times.

Re-installed 10.13.4 over my existing OS, tried the Clover ALC method once more, failed. Tried Method 2 (PCIID and the HDMI kext) but that doesn't work either. Attempted a fresh install using Unibeast method, but Terminal will not allow me to choose HFS+ file system. I was using RehabMan's "startosinstall" procedure, but Terminal would not complete the path/command past "starttoinstall." So I CCC'd my backup SSD to my (previously blank) primary SSD and I'm reset to zero again.

Why no output device?????????

diskutil list shows one in each of disk0/s1, disk2/s1, & disk3/s1.
