This is a comproportionation reaction. Sulfur dioxide acts as an oxidant; sulfide as a reductant.

$H_{2} S (a q) + S O_{2} (a q) \to 2 H_{2} O + 3 S (s) ⏐ ↓$ $H_2S(aq) + SO_2(aq) rarr 2H_2O + 3S(s) darr$

$Sulfide ion is oxidized to elemental sulfur$ $"Sulfide ion is oxidized to elemental sulfur"$ .

$Sulfur dioxide is reduced to elemental sulfur$ $"Sulfur dioxide is reduced to elemental sulfur"$ .

As I recall, the sulfur precipitates from solution as a fine white precipitate.
