Ah, I see. I like offloading things like this to modules, in this case I think IPC::Run would be appropriate, the following works for me. If you think the child might misbehave and not terminate on SIGINT, see the IPC::Run doc section "Timeouts and Timers" on how to time out the kill operation.

use IPC::Run qw/start/;

my $h = start ['play','-q','/home/myname/soundfile.wav'];
sleep 5;
$h->signal('INT');
$h->finish;
