DH & I are confused why all of a sudden anytime we try to play a video you can't understand a thing because it sounds like an echo in a tunnel. Very tinny sort of "distant" sound. Essentially you can't PLAY videos, this is a brand new problem in just the past week. Does this sound like a setting is off? Haven't changed anything, but Dell's customer service guy had me do a lot of things last week when it crashed. Everything else is greatly improved.
