Trouble with Bose Soundtouch 20

Hi,

I have some troubles while playing on a Bose Soundtouch 20 via UPNP/DNLA

First, it needs to be limited to 44/16

And, even in this case, playback goes to end of the track, but does not go on to the next track, volume goes to 0, it does only play one track then stops !

Any idea? thanks !
