Computer problem

OK so i go to play a moive on my laptop and i take note that the visuals are fine and the sound is on que, but the speech is slurred and i notice a faint crackling of the speakers while the sound is going on. i am not sure but i might have done something accidenlly while doing stuff for ventrilo with my sound but i dont think so should i update my drivers or try to run no process while im watching a moive? any suggestions? thanks in advance@!

Try both, if one doesn't work, do the other, and if both don't work, try them together, and if that fails, well, gl and hf.

It is generally advised to turn off the background tasks you do not need while you watch a movie.
