Starting Volumio in combination with the Beocreate gives a very loud pop if you don't change the mixer settings to Volume Software controle and Hifiberry DAC. Then also change startup volume setting to zero. Then, after starting, there is only a minor click to hear because the volume is low. If you do not do this you will hear a loud pop.
A minor issue with Volumio is some clicking sounds when volume is set to zero but only when playing Internet Radio.
The best settings for me at the moment is the original B&O Beocreate software with only BT and Airplay.
