  We investigate general frameworks for calculating transport coefficients for
quasiparticle theories at finite temperature. Hadronic transport coefficients
are then computed using the linear sigma model (LSM). The bulk viscosity over
entropy density ($\zeta/s$) is evaluated in the relaxation time approximation
(RTA) and the specific shear viscosity ($\eta/s$) and static electrical
conductivity ($\sigma_{el}/T$) are both obtained in the RTA and using a
functional variational approach. Results are shown for different values of the
scalar-isoscalar hadron vacuum mass with in-medium masses for the interacting
fields. The advantages and limitations of the LSM for studies of strongly
interacting matter out of equilibrium are discussed and results are compared
with others in the literature.
