Volume control and DSD

Bonjour,
Just upgraded to latest firmware to find out, that there is still no hardware volume control possible under Windows 7 or android 6/8 when playing DSD!
Will you fix this feature in the firmware of this gen KTBD soon?
And will this feature be fixed in the next gen KTBD firmware?
Do you recommend a workaround for this problem?
