Long delay exiting in piped mode on Rpi2

[dcm1104]

I am trying to transmit portions of standard NMEA sentences like so:

pi@raspberrypi ~/gpslhf $ echo "4135.1898,N,09342.6185,W" | minimodem -t 1200

I get a long delay after the end of the tone -- between 10 and 12 seconds before the command prompt is available again. The exact same command on my laptop exits as soon as the tones complete.

The behavior is the same whether the audio device is an external usb, built-in, or through the HDMI.

BTW -
pi@raspberrypi ~/gpslhf $ uname -a
Linux raspberrypi 4.1.19+ #858 Tue Mar 15 15:52:03 GMT 2016 armv6l GNU/Linux

I just tested this on my pi zero and it's working fine. However I don't have pulseaudio running, so I'm using the -A option for alsa playback.
echo "4135.1898,N,09342.6185,W" | minimodem -A -t 1200

I have minimodem 0.8.1 running from apt-get. I don't have a -A option. I'll see about getting a later version running.
(I'm assuming 0.24 > 0.8.1)
Thanks yodakohl
