hiya guys new to the forum, i recently brought out a contract with o2 for a htc one, got home set up all my notification sounds, i was getting sound for my facebook posts, but the next day i turned my phone on and they were coming through but no sound, if i get a notification on there my phone just vibrates but for other stuff i get the sound, if i get a message on fb i get a sound too, not sure why it has done this and im not sure how to change it could anybody please help me would be great thank you.
