Hello,
I’m French.
Here is my configuration : VirtualBox 5.2.18 , Debian 9.5 and Windows 10Pro.
I test Volumio under debian before buying a raspberry pi 3B +.
For my installation, i’ve taked this help : github.com/volumio/Build/wiki
It’s hard but I’ve completed this 
Volumio is On : I’ve the screen configuration (in 6 steps)
But mouse is Off and also keyboard too 
Under debian the mouse is active and the keyboard too !
If you have a solution, help me, please 
To test, I suggest you:
Download the x86 image write an usb key and boot your computer with it.
Or
Convert the same image for virtual box using
VBoxManage convertdd input.img output.vdi
and boot virtual box with it.
Hello balbuze
Thank you for your help.
I try this tomorrow and i reply here.
Hello,
I try this
Image is here : 
Volumio Audiophile Music Player for PC (X86/X64) VERSION: 2.411
My USB Key is 8Go
I take Win32DiskManager for install image.
I boot.
I’ve the beautiful logo Volumio and the log (log : root, password: volumio) and nothing, no volumio.
What else
Hello,
Volumio run 
Yes
Good !
But the first solution should have work.
Don’t forget Volumio is designed to run headless. You don’t have to log in it using a keyboard. Use another device (computer, smartphone) to connect to it.
