What sound drivers does Haiku R1A4 support?

I am having to use OpenSound on my system to get sound at this point.

No matter what I did I could not get sound to work with the stock install of Haiku R1A4.

Does Haiku supposed to support this nVidia driver?

My Listdev gives me:
vendor 10de: Nvidia Corp, device Nvidia 0774: MCP72XE/MCP72P/MCP78U/MCP78S High Definition Audio

Did I jump the gun by installing OpenSound or did Haiku supposed to work with this nVidia audio I have?
