Yesterday for the first (and so far, only) time, the player didn't produce any sound after unpausing. The song was playing, as evidenced by the time display and animated visual, but there was no sound. Whenever I then paused the song, I would hear a short snippet of sound, but after unpausing again there would again be no sound whatsoever. Even turning the player off then on didn't solve the problem. I had to power cycle it (by pulling it from the sled; this was in the car) before it would resume playing normally. I don't remember which song it was, but I do know that I had played it several times before without problems.
