No Audio Devices - AppleHDA Realtek Audio

[Browny98]

Audio codec appears to be disabled in BIOS, verify BIOS/.../HD Audio/Ensabled

Had a look in the BIOS now, the HD audio is enabled within the BIOS....

I don't understand why there isn't any Codec ID...perhaps I haven't installed a codec correctly?

I've had a look to see if there's a reason for the codec not appearing, if I run Clover Config and mount a new EFI I have found the following kexts to be added....seems like there's a lot going on at once?

When there is a codec, 3 patches are required for 1150 onboard audio and 2 parches for HD 4600 HDMI audio.

When there is a codec, 3 patches are required for 1150 onboard audio and 2 parches for HD 4600 HDMI audio.

So is this evidence to suggest that there is a codec? But it isn't perhaps being recognised?
Or does it suggest that the codecs aren't being patched correctly?

I've ran the audio_codec detect command and it also confirms no codec found, is there anything else I can try at all?

I don't know if the codecs aren't working or if they haven't been installed correctly?

So Ive spent some time cleaning up old EFIs and also ensuring that the AppleHDA.kext was and is native. Having done this and then having applied the AppleALC.kext has now allowed the audio codec to be recognised as attached. Do you want the files previously attached to all be updated now?

This is the issue, I removed all existing patches including cloverALC and so now there is only AppleHDA installed. However upon restarting the computer, I have then chosen to follow your guide again from the start so that I have essentially, the template that your guide has set out. I have attached the new files below.

I have also produced all the files prior to following the guide as well if you needed those?

I'm back to not having audio again. I've tried completely uninstalling and reinstalling all audio related fixes and the cloverALC script isn't bringing my devices back. I'm at a loss for what to do next. Any help would be greatly appreciated!
