I have bought a Xduoo TA-10 and getting cracking / clicking noises whenever a new song is played. E.g. I listen to song 1, it ends and right before song 2 starts there is a cracking / clicking noise . The sound is coming from the device AND the headphone. When I turn on the sound a little it gets really annoying in the headphone. Is this normal? Also I noticed a pretty big noise floor. Are these issues maybe related to the tube or is the device broken?
