One guess: On playback start, buffers are empty and can accept lots of data. This could result in some busy loops until enough data is read to fill the buffer. If, for some reason, the disk read requires much CPU time, then the busy loop will actually slow down the disk reading too. Maybe, in case of softdevice, this is oscillating: A busy file reader takes CPU from decoding, causing decoding to stall. And as soon as the decoder is catching up, maybe by dropping frames, the file buffers run empty causing the file reader to busy loop again. (speculative, though) Cheers, Udo
