### Description

We compute the equation of state of isospin asymmetric QCD at zero and non-zero temperatures using direct simulations of lattice QCD with three dynamical flavors at physical quark masses. In addition to the pressure, the trace anomaly and the approach to the continuum, we will particularly discuss the extraction of the speed of sound. Furthermore, we will discuss first steps towards the extension of the EoS to small non-zero baryon chemical potentials via Taylor expansion.
