usb stick with x86 Volumio problem

I try to get Volumio working but no succes. I unzipped the img.zip in Debian with the Debian unpack option. Flashed the .img to a usbstick with Etcher and rebooted.
It starts but then I get the message:

sh: can’t access tty: job control turned off

I tried starting normally and uefi but no difference. I tried an unformatted and formatted usb stick.

What is it I do wrong? Do I need to unzip the img.zip in a special way?

I use the usb-stick on an Intel I3 pc with no additional graphics card. In some online info I read ctrl-c might help but that does not work for me.
