While a song is playing on the Sansa, the playback just stops without warning. There is nothing that can be done to resume playback of the current track. The only available options from that point are to skip forward to the next track; hold down the rewind button until the previous track starts playing (skipping backward to the previous track does not work).

In an attempt to fix  FS#8049 , a code change by nicolas_p on 30 Oct 17:24 seems to have exposed a new flaw in audio playback on Sansas. According to saratoga, "the MOB patch makes an assumption about the ATA setup that does not hold because of the odd way the Sansa's flash is organized. As a result, the encoded audio buffer never refills and playback simply stops when it empties."

While the playback was frozen on my Sansa e280R, I copied down the following information (not sure if there is anything useful here):
