I have a Sansa Fuze 8GB. On some long tracks, especially Rhapsody subscription tracks transferred to the Sansa, a ticking or clicking noise, about 2 clicks/second, starts to appear about 12 min. into the track. It gets louder and more insistent. At 15 min. the track is unlistenable. I have found that if I hit any button on the Sansa (like the center button), the noise goes away from about 15 seconds, then comes back again. Also, the tracks play through fine on my PC. Therefore I suspect this is a problem with the Sansa. Any idea what’s wrong? BTW the firmware is V01.01.11A.
