Please check "Developing IP Multicast Networks", by Beau Williamson,
chapter 12 on Auto-RP. It works just fine with sparse mode. There are
some good points brought up below but that doesn't mean you must use
sparse-dense, it will work with sparse mode (but I agree, why limit
yourself with sparse, use sparse-dense).
