Disable snapchat video recording sounds. (Maybe by deleting sound files?)

Hello. So I have this problem with my new phone (Huawei Honor 7) that whenever I record a snapchat video it plays a sound when it starts and stops recording. I did not have this issue using my old phone which is a Sony Xperia Z1. The sound is comming through the speaker even if my heaphones are plugged in and my sound is muted.

I thought abou deleting the soundfiles but I have no idea where to look for them. Does anyone know where the sounds are saved? I have also not rooted the phone if that is of any importance in this case.

Thanks alot!
