Thank you for all the great work - at last after 2 years gathering dust I can finally use my pogo pro to play music! I have it running as a DLNA audio renderer using mpd and umpmdcli. I have a separate Plex server as the library and upnp control on Android. Currently I only have a cheap usb audio dongle but will upgrade to something better soon. I had to compile upmpdcli from the souby anto - Debian
