I pressed Quit and an error appeared: “EOF in pipe to mpg123, maybe it died?”
At the moment this is apparently normal. Stop and Quit effectively do the same thing, but Stop is the recommended way to exit. (Actually, letting the stream play itself out is the recommended way to exit. See question 15.) 11. Pause doesn’t pause immediately. No, it can’t. The player has to play whatever is in the buffer before it can pause.
