My Mogul randomly mutes itself. Please help!

[Gunflight]

The phone will be working fine and then I go to use it and there is no sound at all. I mean nothing. I can’t hear people on the other end of a call. It won’t make a sound in any program and won’t ring. The volume is all the way up. If I restart the phone it works fine for a while and then randomly does it again. The problem is I don’t know when it has stopped making sound. This is really frustrating because I miss calls and messages. If someone knows how to fix this issue please let me know.

Thanks.
