Previously AudioPlaylist::read always returned the timecnt that it was supposed to read into the buffer, regardless if the given number of samples was read. The check in DiskReader::refill_audio `if (nread != to_read)` never triggered. This can happen when changing an audio-region's time-domain to music-time (glue to bars/beats). Region-length (beats converted to samples) can exceed the actual audio-source length (in samples).
