Annoying?

I love snapchat but recently the sound on mine hasnt been working... whenever i talk and then watch the video all you see is my mouth moving and there is no sound.?This is getting on my nerves. I have deleted the app and logged back in but it still doesnt work. and i also snapchatted team snapchat but all i get is that stupid link. Snapchat needs to fix these stupid problems. They need to ACTUALLY reply instead of sending a stupid link. Please fix this....

Cooliooooooo! about Snapchat, v10.4.2.0
