Silent play can be caused by a lot of other things too, such as miscalculation of the buffer watermark for example.

The read timeout has nothing to do with how much data has successfully been read. As I explained earlier, each read operation is atomic. It either succeeds completely or fails completely. It cannot fail yet report some amount of data as read.
Giving up the read 2 seconds before the buffer runs out simply means we have 2 seconds to (try to) read the next file before playback stops.
