When I had "Serenade DSD" connect my android device(SONY Xperia L C2015), I let Poweramp play a song(FLAC, 44.1khz, 16bit), and then I could listen to music from "Serenade DSD". However, the music usually stopped in several minutes. The sound stopped but the track in Poweramp still played. P.S. "Serenade DSD" is a affordable and portable reference grade USB DAC.
