I play my music thru a receiver with the wires plugged into the audio in/out of the back of the receiver. I can hear my Ipod playing music. I can't hear Spotify on my Samsung SM-T110 tablet. I can hear Spotify play music when no wires are attached to the Samsung and I can hear music when I plug in earphones. I just can't hear music from the Samsung when I plug it into the receiver. A friend brought their tablet over and they can hear music thru my receiver so I am thinking a setting on the Samsung got changed?
