Ok. I installed your app on another device (S4 Mini). The playback from my Twonky server worked fine. Yet there is another problem. The songs are listed alphabetically. They play not in the correct order.
I have a problem with a NAS called Qnap TS-212 with TwonkyMedia 18.104.22.168 installed. The Twonky server works fine on all devices. With SoundSeeder not all files are playable from the Twonky Server. Often there is “playback failed” error.
