Can I control audio/vibrate/DND on iOS remotely? I have 2 iPad minis and an iPhone 6+.  

Sometimes I like to hear the "ding" of a message or mail, sometimes I dont.  Its a pain to go to each device to change the settings.  Is it possible to set a remote iOS device to DND or turn the volume/vibrate/DND on/off from another device? 

FYI, I do not have a Mac, just Windows or Linux.
No. Per iDownloadBlog.com's article on using "Do Not Disturb" in OS X Yosemite:

Do Not Disturb settings do not sync across the Mac and iOS devices.
