Unity YouTube Channels

Hi,

I’m looking for some informative YouTube channels pertaining to Unity. The official channel has a meager 6 videos. I know there must be some good, professional and informative channels out there; anyone know of some?

I found this channel that has some really basic tutorials up on like triggering audio, making simple quests, spawning objects etc. All small things you could use in your game that are quite helpful. Here it is: 2KMIXEDIT - YouTube
