They only pan the backs of the heads of the audience at the beginning. Then at the end, they show the family of the person in the final round and a few audience members are around them. Rarely, they'll show some audience shots at the end if they have extra time. Today, they had no extra time. So at the most, you might be able to see the back of my head.
No, which was really disappointing. The "audience" yelling "WHEEL. OF. FORTUNE." at the beginning is a recording. The actual audience doesn't get to yell anything. I was looking forward to that part.
