Airplay start volume always -69dB

[spater]

Would be great if someone could help, whenever I connect with a device via Airplay the volume jumps down to -69dB on my Expert Pro, can I change this anywhere? In the configurator I have set all inputs to -40dB for startup.

Same happens for me. I don't think it is 'fixable', Airplay must have some default volume setting that can't be changed (or at least I haven't found a way).

Out of interest, is your Expert Pro switched on or off before you start the Airplay session?

Reason for asking, for me this happens:
1) Expert pro switched on -> connect iPhone to Expert Pro via Airplay -> music plays at -69dB
2) Expert pro switched off -> connect iPhone to Expert Pro via Airplay -> Expert Pro wakens form sleep mode -> tries music playback at -40dB (default) -> no sound from speakers -> I manually switch AirPlay sources from Expert Pro back to iPhone then back to Expert Pro -> music plays at -69dB

Curious to know if option 2) is what you experience too. It only takes a ~10 seconds to resolve but I can't imagine it's the user experience Devialet intended.
