Garry's Mod Mouse and Audio glitch

Hello everyone. Yesterday me and a friend joined a TTT server. We both played on the server for about an hour then all of a sudden we when people talked we could only hear white noise and if we tried to move our mouse it would just spazz out everywhere. We thought it was the server and stopped playing but today when we went to play on a different server the glitch continued. We tried several servers with no success.


Thanks everyone
