I had problems with this as well. Sometimes I got the letter but Siddgeir would not be sitting at the throne. He along with his housecarl and steward were stuck in the room right of the throne. Siddgeir didn't even have "Jarl" in front of his name. Finally after a few new games and reading as much as I could find on this (I had not joined any side in the army, I had not joined the dark brotherhood), I had   Arise - Chapter 1 - The Black Sacrament mod which right off the bat of starting a new game wants you to find 5 things.

I finally uninstalled it and tried a new game again. I got the letter and Siddgeir is sitting at the throne as Jarl and gave me the quest.

Hope this helps others.
