my config.plist is almost the same as in this post
Now working the clock. But now no sound i tried VoodooHDA and AppleALC but not at the same time. With applealc tried the alcid layout codecs, no sound. I tried the DSDT patches AZAL to HDEF and HDAS to HDEF and tried without this patches.

sound works - built-in codec, and usb "sound card for $1 from aliexpress"
hdmi did not check.

Hello svk77,
I found a Solution for the VoodooHDA.kext Problem, what is taken me 6 Weeks after searching Google und posting in other Forums.
It is the FSB Frequency what must be correct setting in OpenCore config.plist
I give you an Example for me AMD FX 6300 with 3,5 Ghz and the FSB with 200 Mhz.
I used CPU-Z in Windows the get correct FSB
The correct is exactly 200.38 Mhz, but make 200 Mhz for better calculating.
So now you have everthing you need to know.
Step 1 - Open your config.plist.
Step 2 - Go to PlatformInfo - Automatic, in the Sample the Automatic is setup to Yes. Set it to "no".
(Otherwise the Information from "PlatformInfo -DataHub" will have no Effect!!!!)
Step 3 - Set "ARTFrequency" to your CPU Frequency, in my Case 3500000000 hz = 3,5 Ghz.
(The Entries abut FSB and so on are "Hz")
Step 4 - Set "InitialTSC" also to your Frequency, in my Case 3500000000 hz = 3,5 Ghz.
Step 5 - Set "FSBFrequency" to your Bus Speed shown in CPU-Z or an other Tool of your Choice, in
my Case 20000000 hz = 200 Mhz.
Step 6 - Start with your USB Stick and check if your Sound works correct. If your Sound is to slow
and is "chopped - German - abgehackt", then set go the half of your FSB down, lets say to
10000000 hz = 100 Mhz. That is the Way I made it. Finally went down to "60000000 hz" and
the Sound is good. Off Course you can go on and make it more perfect with more small Steps
by setting down the FSB Value.
When are finish, your Entries look like this (only for the AMD FX 6300):
I hope I could help, I never forget who helped me.
