super sound - problems with NAS - insufficient Windows compatible

I operate the device on a Synology DiskStation. The integration as a media server works, but that the folder structure is not displayed. Strangely, however, title, album, artist. That's when thousands of titles, but very annoying. You have to connect the NAS as a network drive with login name and password, everything works as desired. As far as that's not bad. But but !!! after a few days operation, the NAS is not mounted correctly. The Devil app shows the NAS "offline" although the NAS is running and can be accessed from the PC via wifi. Titles are displayed but can not be played. Delete NAS as a music resource, integrate new and scanning: measure. This sucks easy and takes. My wife can not be expected - you are no longer using the Raumfeld Connector.

Pity is that in Windows Media Player (Win 8.1) the "Play To" is not working properly. The Raumfeld Connector appears as a device, a playback is also possible, the volume can not be changed during playback. Press stop, change volume, press Play and then "Device error" The Raumfeld Connector so is not really compatible with Windows. If only it were a Windows app to control the Windows Phone and / or PC would be .....

Actually, I would have to return the unit, but as I said, the sound is perfect. So I'll turn a few laps with the devil Service so that at least the NAS integration remains permanently.

Addendum:
With the app "BubbleUpnp" the NAS is found properly and the Raumfeld Connector is driven as a renderer perfect. Unfortunately, then missing the devil Internet radio and the sound settings. Have the impression that the devil-app programmers still have work to do. The app is not good!
