So, following the advice from Syed in this thread, I was able to do a temp fix. Adding ~300 milliseconds of sound to the end of the sound being played does stop it from being cut short. However, this is extremely impractical as I have 2000+ sounds.
Is this a known bug in Android 2.2? Has anyone else experienced this problem?
