My setup consists of a Wiim Mini connected via TOSLINK to an amp, and a couple of Audio Pro C3s connected as slaves to the Wiim Mini. The FIxed Audio Output feature is active on the Wiim Mini.
In this configuration, the Wiim Mini volume control on the Wiim Home app is disabled. What I don't understand is: why is the "Group volume" control disabled as well? Would it be possible to leave it active, in such a way it operates only on the volume of the slaves?
Thank you! :-)
