I generally play a game with all options on. Listening to something else will be massively distracting to me, so that's not really an option. I turn off music or sound if it's annoying enough, but most of the time I won't. Silent games are fine with me, as well, having played a lot of text adventures in my time. A game like If on a Winter's Night, Four Travelers is made even better by the music and sound design. (I doubt it could be done much better than that one.)
Voices. I completely understand Formosa Falanster's point of view, and I can agree that very text heavy games may not always benefit from being voiced. However, I think games with a lot of dialogue can be better from it. This is down to how well it is been done, both acting and how well the voices fit the characters. A game like Pedro's Adventures in Spanish, where the whole point is to learn Spanish while playing, needs its voices. Games with voices also will be playable to people who can't read very well, either dyslexics, people with eyesight problems or in the case of children's games. Good voice work may also add significantly to a game's atmosphere, like The Garden of Hades, or it can be used humourously, like The Detective Boiled-Hard games. But it's a good idea to have an option to toggle voices on/off, especially for quick replays of games or part of games.
