The alarm sound will only play once. No sound or file selected will play after the first one, until NCIDpop is restarted. It's almost as if it needs to be "rewound" although, if that was the case you'd think it would play a different .wav file. But it doesn't.
I've tried it on a 64 bit MINT 17 system and a 32 bit MINT 17 system with same results.

Confirmed that this is an issue with the OpenJDK java version that ships with Linux Mint 17.3 Cinnamon. In my case, I downloaded the 64 bit version of Linux Mint 17.3 Cinnamon and ran as a live session
I was able to fix the issue by installing the latest version of Oracle Java.
For reference, here is the version of OpenJDK that I found in Linux Mint 17.3 Cinnamon:
mint@mint ~/Desktop/NCIDpop $ /usr/lib/jvm/java-7-openjdk-amd64/bin/java -version
java version "1.7.0_85"
OpenJDK Runtime Environment (IcedTea 2.6.1) (7u85-2.6.1-5ubuntu0.14.04.1)
OpenJDK 64-Bit Server VM (build 24.85-b03, mixed mode)
And here is the version of Oracle Java that I installed:
mint@mint ~/Desktop/NCIDpop $ java -version
java version "1.8.0_77"
Java(TM) SE Runtime Environment (build 1.8.0_77-b03)
Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode)
Also, for reference, here is the output from the version of Linux Mint that I installed.
mint@mint ~/Desktop/NCIDpop $ cat /etc/*release
DISTRIB_ID=LinuxMint
DISTRIB_RELEASE=17.3
DISTRIB_CODENAME=rosa
DISTRIB_DESCRIPTION="Linux Mint 17.3 Rosa"
NAME="Ubuntu"
VERSION="14.04.3 LTS, Trusty Tahr"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 14.04.3 LTS"

HOME_URL="http://www.ubuntu.com/"
SUPPORT_URL="http://help.ubuntu.com/"
BUG_REPORT_URL="http://bugs.launchpad.net/ubuntu/"
cat: /etc/upstream-release: Is a directory
So, in short, installing Oracle Java should resolve the issue.
