Help with Triple Boot

Specs:-

Gigabyte Z490 Vision D

i9-10900k

Sapphire 5700 XT Nitro+

3 X WD SN750 1TB

OpenCore 0.6.2 - Catalina 10.15.7

Each OS is installed on a separate drive. macOS and Windows work perfectly, Ubuntu is the problem child. I currently have 2 issues (They are present on both 18.04 and 20.05). OpenCore doesn't seem to be able to boot into Ubuntu without either adding the drive in Misc/Entries or BlessOverride (both exhibit the same issues)

  1. Sound card not being detected. Only sound card displayed is the HDMI adapter. Internal not being seen.
  2. Can not reboot or shutdown. Goes through the motions, all pid's are killed, all filesystems dismounted, then it just sits.

I should mention that non of these issues are present if i boot directly into Ubuntu from the bios. Anyone have any experience/insight as to where i might begin looking?

Thanks
