MinimServer, BubbleUPnP, JRMC and Oppo combo not working as expected

[haggis999]

I want to use BubbleUPnP on my Samsung Galaxy Note 2 'phablet' to control the playback of stereo FLAC files served by MinimServer from my Synology NAS. I could use this software to 'push' the files directly to my Oppo BDP-105 media player but that does not yet support gapless playback of FLAC files via DLNA. However, if I push the files to J River Media Center on my PC, which has a USB connection to the asynchronous USB DAC input on the Oppo, then gapless playback is achieved.

So far, so good. However, this combination of MinimServer, BubbleUPnP, JRMC and Oppo does not handle playlists properly. Sometimes a playlist will stop after the first track. On other occasions, it might jump from the end of track 1 to the start of track 7. The behaviour appears to be quite random. Note that I am not using any shuffle options.

I have no idea if MinimServer is to blame but any suggestions for how to track down the cause of this problem would be much appreciated. I have made a similar post on the BubbleUPnP forum.
