Clean sand doesn't smell, but the poop dust in the sand rots and stinks when wet.
That's why, IMO, dry organic material is better than sand, with the carbon rich wood/straw/etc. neutralizing the nitrogen rich manure.

I'm not a fun of sand, but IIRC, what's recommended is washed construction sand, coarse-grained and free from fine dust.
It only works if kept perfectly dry. Excellent ventilation helps.
