Contrary to the description at digitec (2.1.2023) and contrary to the information in the technical specifications in the instructions for use, the unit does not touch DNLA. Neither in the menu nor in the UNDOK app does DNLA appear as a source. It is also not possible to stream music from an external player to the unit. It does not even appear in the list of possible players (e.g. in BubbleUPnP). Ergo, the Noxon A580 cannot do DNLA/uPnP.
For me, by the way, this is the reason for a return.

This would have to be connected to the A580 via the network.
