Thanks @freesby! The audio fix worked right away. As for the graphics, all I've done so far is change my system definition to iMac 18,1 as you suggested. Already there's an improvement, sort of. It seems now that the output is always active. It just goes to a black screen when the energy saver kicks in, but the monitor stays on. Where do I need to patch the connector types? That's the only part of your instructions I couldn't follow because I wasn't sure how to proceed. I searched a bit and there was some stuff about using a MacPro definition, but I didn't want to try that for fear of wrecking things further.
Yeah. By the way I forgot to mention that the HD 630 iGPU can't wake up from sleep. This seems to be broken. But the monitor might turn off after going black and you may be able to wake it up. IDK if this works for any monitor.
Regarding the patch for the connector types, you don't need any patches if the system is loading the default ig-platform-id and ID for HD 630. The AppleALC kext automatically patches the connector types for HD630. You might try with ig-platform-id 59260000 to see if that improves anything but you will have to find the appropriate patches for the connector types, that is, change the DisplayPort type to HDMI.
