Soundbar disappears

[AdelieHeier]

For the past week my iPhone has had problems playing songs via spotify. For some reason the sound would just disappear as well as the soundbar. The only way to get the sound back is if I unplug the headphones. I've tested my headphones on other devices and then it's no problem. Does anyone know how to fix this? I've reset my phone and downloaded Spotify again.

Thanks
