Pop noise when receiving a Notification

I just got my moto x Pure a few days ago and i noticed when i receive a text message i get this pop noise after the notification sound stops playing. I went in the settings to change the notification sound and as im switching between them they all have a pop noise always after there done playing or sometimes before playing. If i try to change the ring tone it doesn't happen, they start and end fine with no pop noise. I remember having a similuar issue with my nexus 4 and to remedy the situation i would disable touch sounds and vibration but it doesnt seem to help with this phone.

Someone on reddit said he had the same issue. Anyone else experience this ?
