@piglet: I don't know if you were in the group I was in last night, but make sure to hit options, go to social and join the group chat from there. I don't know if you tried that, but if anyone else is unaware then that'll get you into your group voice chat. If you have auto join voice channels off, you have to do that manually. I was in a group with 4 people from the community last night and only 2 of us were in the group voice chat. I don't know if they just didn't want to be on voice(which is fine) or were unaware of the group voice channel. So, I'll just throw this out there for anyone reading it.
