My three Raspberry Pi 3B+ and their HifiBerry DACs+ PRO are attached to a 12-channel multi-zone amplifier Daytonaudio MA1240a. On the Raspberries, the piCorePlayer softwre is installed.
The amplifier provides a standby mode with an Auto Turn-On feature. It awakes as soon as some music on one of the raspberries is started.
According to the documentation, the Auto Turn-On Sensitivity is 13.7mV.
Unfortunately, the amplifier goes to sleep when I reduce the volume to <30%. Below 20%, the sound is not hearable.
Is there a Hifi Berry setting I could use to overcome this issue?
