How to send audio stream to recognized dlna device?
after basic installation of Serviio (1.5.2) in Ubuntu Linux and a few tries to get it sending audio streams to my Icy Box Air* I got a bit lost and hope someone can help me out. I guess it's an easy question, but I'm not experienced with dlna and serviio, yet...
What I want to do:
- Play music (mostly mp3 files) from my Linux/Ubuntu PC (as audio stream) over wlan on an Icy Box* which is connected to the speakers. The PC should completely control the playback, the Icy Box should just receive the audio stream and send it to the connected speakers.
What works (basic tests):
- The Serviio console lists a "Generic DLNA profile" with device name wifi_music for the ip address of my Icy Box, status "green".**
- I have mp3 files in my shared folders library path and I can play that music with Serviio MediaBrowser - though only locally on my Linux PC, not remote on the Icy Box... (where I want the sound)
- If I use an android tablet with the "allcast" app I can use it to connect to the Icy Box and play an mp3-audiostream with good sound. So my basic hardware setup (Icy Box over wlan with speakers, dlna etc.) works nicely.
I just want to be able to do the same audio sending like with android/allcast with my Linux PC and am hoping that Serviio can do that...

...basically I am missing an option or something like that in the Serviio MediaBrowser (or elsewhere) to say: Send the audio stream to your detected device "wifi_music" (instead of playing it locally). I think Serviio can do that, right? Or should I use other tools...?
Thanks for any help!

*: (Icy Box IB-MP401AIR features: DLNA, UPnP and Airplay support, controllable via smart phone and tablet PC by using free UPnP APP's (ANDROID) or AirPlay (iOS))
**: With the "gupnp-universal-cp" scanner on my Ubuntu Linux I can see the "wifi_music_streamer" (the IcyBox) as a playing device (speaker icon) in my local wlan ( type: urn:schemas-upnp-org:device:MediaRenderer:1). It lists 3 general entries for that upnp device - Rendering Control, Connection Manager, AVTransport.
