Are you sure, I checked with aplay, it seems to me work for me on Fedora

$ aplay test.wav
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
^Z
[1]+  Stopped                 aplay test.wav

It did pause the file and I was able to resume it from the last
position.

FWIW:
$ aplay --version
aplay: version 1.2.6 by Jaroslav Kysela <perex at perex.cz>

Pause the stream should be apt behaviour, unless Takashi or Jaroslav
have better ideas
