Phone randomly starts playing music

[ETE]

Hi - occasionally, my Z2 starts to play music on it's own through the walkman app (not that I really have any music in there except the default tunes delivered with the phone) which can be somewhat annoying/ inappropriate when sitting in a meeting. 

Any setting I can manage that with?

Clear data for smart connect app.

Thanks. I'll attempt to do so - not sure precisely how...but will try.
