New Automatic HDMI Audio Script Released

Not open for further replies.
IOReg reports system status only, not necessary.
I figured out why the automated script failed. I was stupid and forgot to mount the EFI partition. But even after running it, it says no HDEF found. I run it anyway, and it gave the attached results. Also, I got the IOReg stuff you wanted.

Just installed with EVGA GT740 SC 4GB + Sierra 10.12.6, and it's worked perfectly. Like magic:) Thanks Toleda!

I did get confused at first, when running the script, as it reported no audio codec detected, which I thought meant it wasn't compatible, and I cancelled the install. The second time I just typed Y to continue, and it was fine, even downloading a file automatically to complete the install.
Thanks again!
I ran the latest script but HDMI did not appear in sound preferences. Can you help me?
I have DVI, HDMI and DP ports on my mobo. TV is connected to HDMI. I did not choose any audio options in MultiBeast. For integrated ALC887 chip I use AppleALC.kext and it works. But I also need possibility for HDMI-audio.
