X randomly starts playing a sound file

[Fuimusbruce]

So my X will randomly start playing a sound file if I push the volume button on my bluetooth, also when I plug it into my data cable on my computer. Any ideas? Sometimes doubletwist is the app playing, but just now I couldnt see any app running but it was playing a sound file. (usually these sound files are parts of audio books I have downloaded.)

am I the only one who has this issue?
