There are a few settings to adjust for the Vanity Pro to work with Roon. You have to go under Audio settings and adjust the buffer to 50ms. Also the resync buffer needs to be set to 50ms under the advanced settings, otherwise I got pops with my dacs. Finally select 7.1 also under advanced setting and name the driver Vanity Pro.
I have an Asus Hero XIII mother board. I chose Asus products because they typically support all common sample ratesm 24/176.1,/24/192. 24/48,/24/96 etc.
