Using x[0s..1s] gives out an error. Is this a known broken feature? I am surprised as it is extensively used in the readme.

stream = loadstreaming(fname)
LibSndFile.SndFileSource{FixedPointNumbers.Fixed{Int16,15},String}
  path: "/nvme/ml4a/Tango_project/tango-analysis/flacs/DE0D1DF3D0EBD28F.flac"
  channels: 1
  samplerate: 22050Hz
  position: 0 of 3197250 frames
            0.00 of 145.00 seconds

stream = loadstreaming(fname)
x = read(stream, 4s)
close(stream)

with the latest version this seems to be working:

julia> using FileIO: load, save, loadstreaming, savestreaming

julia> using LibSndFile, SampledSignals
