  We analyze the evolution of hydrodynamic fluctuations for QCD matter below
$T_c$ in the chiral limit, where the pions (the Goldstone modes) must be
treated as additional non-abelian superfluid degrees of freedom, reflecting the
broken $SU_L(2) \times SU_R(2)$ symmetry of the theory. In the presence of a
finite pion mass $m_{\pi}$, the hydrodynamic theory is ordinary hydrodynamics
at long distances, and superfluid-like at short distances. The presence of the
superfluid degrees of freedom then gives specific contributions to the bulk
viscosity, the shear viscosity, and diffusion coefficients of the ordinary
theory at long distances which we compute. This determines, in some cases, the
leading dependence of the transport parameters of QCD on the pion mass. We
analyze the predictions of this computation, as the system approaches the
$O(4)$ critical point.
