Audirvana Windows 10 Volume issue Devialet Expert Pro

I am using Audirvana 1.3.8 (1064) on a Windows 10 PC. My settings are: UPNP to Devialet Expert 250 Pro. There is an issue when I control the volume with my Devialet remote. The volume control depends. When I mute the Volume in Audirvana it works, but after restarting the PC the mute in Audirvana is lost! What can I do?
