TempoTec Sonata BHD (non pro) volume control issues under Windows 10

[avm]

Hi there!
I was wondering if someone else has experienced this issue with this Dongle/dac: I can't control the volume properly/gradually with Windows 10. It's either 100% volume (starting at 2% and higher) or 0% (at 0%). I'm a bit disappointed since I also own the BHD pro version and it doesn't behave like this.
Is there anything I can do about it?
Cheers.

My Tempotec BHD DSD is the same, but I usually adjust the computer to 100% for a DAC/Amp with independent volume control.
