Stuck in RAMPlay

I mad a complete reinstall of my Volumio on a Rasperry Pi Model 1 B.
When I mount my Nas and start creating the new Music DB it starts with the Webradio which works fine and the gets stuck in RAMPlay.
I let it work for more than 24 hours, it was still stuck in RAMPlay and didn’t jump to my NAS mount.

Any ideas?
