Well, I don't know if it's the 10.11.4 update or the changes that @RehabMan made to
HP-ProBook-4x30s-DSDT-Patch to support it, but the webcam now wakes properly with the system after sleep! My audio stopped working after the update, and I saw that @RehabMan had added updated the kext used to fix audio so I updated the rest of the hot patches as well, and oila! Webcam now wakes after sleep!
Just in case anyone with a similar system needs it, I've attached my CLOVER folder. There are no direct DSDT edits; only @RehabMan's SSDT hot patches. I can provide a list of additional kexts if needed, as well. The only part of the system that is not working is the SD Card Reader, but given the wide variety of SD reader hardware out there, it's probably not feasible to patch it. I may give it a try some day, but today I revel in a fully operational Hackintosh Laptop!
Many thanks, @RehabMan!
