Title:
  arecord -d never completes and creates hundreds of files

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  in Ubuntu 15.04 arecord seems not to work as expected:

  arecord -d5 -Dhw:1 -twav -r44100 -fS32_LE -c2  /tmp/msplaysweep.wav

  this is supposed to stop after 5 seconds but instead runs forever creaeting continously new files in /tmp. This is 100% reproducible for me on 2 sound hardwares (internal sound card and USB sound card).
