My newly bought Sansa Shaker has problems playing SOME MP3 songs: they play very slowly, I would say about 1/3 the normal speed. I have about 80 songs on it, and only 4 are played slowly. When I play those problematic songs on my computer, they play at the right speed. Those songs were originally ripped from an audio CD, but other songs that were ripped from that same audio CD play just fine, so I don’t think the problem is with the ripping.
I tried deleting the songs on the Sansa and retransfering them from my PC: same result, i.e. slow songs.
I did check the battery, I even put a new battery in it. It didn’t help.
Any idea folks ? Do I have a bad unit that I should return, or could there be something wrong with the encoding/decoding ?
