We discuss the results of our current eorts in using p-mode frequency measurements obtained from SOHO MDI "medium-l" data for addressing the accuracy of recent versions of the equation of state and the chemical composition of the solar convective envelope. We implement two diagnostic techniques, which supplement each other: (a) direct calibration of the parameters of the adiabatically-stratied part of the solar convective envelope, with using the p-mode frequencies directly and with using group velocities of surface waves inferred from the p-mode data, and (b) a constrained iterative structural inversion. All our results support the downward revision of heavy-element abundances in the solar envelope.
