Set the opus codec to use discontinous transmission (DTX). DTX only transmits data when a person is speaking. Setting this to
com.meta.horizon.platform.ovr.enums.VoipDtxState#Enabled takes advantage of the fact that in a two-way converstation each individual speaks for less than half the time. Enabling DTX will conserve battery power and reduce transmission rate when a pause in the voice chat is detected.
