Intel Nuc DC3217IYE almost fully working.

Spent the evening installing Vanilla on my Nuc. Went smoothly. I still have a few issues to iron out if you have any ideas, that would be great.

1. The only audio out from the NUC is via hdmi. The video card is Intel Hd4000. Graphics side is working fine.
2. Using a Bluetooth WiFi combo card. Bluetooth is detected but a scan picks up sod all.
3. Odd one. Imessage works, but videos bei g sent to me won't play. Black box with play button crossed out.

Any ideas on the above? Vanilla has already shown a small performance upgrade.
