I'm having some problems with wav files playing using the AM335x BSP. I'm hoping someone else has run into this before. I'm trying to add audio to my application by playing some built in sounds from windows. the longer sounds like startup.wav play just fine. But shorter ones like menusel.wav (only 20ms long) don't play at all or sometimes play twice. I found that if I edit the file and add a delay at the beginning of the file to delay the sound by about 75ms, it will play every time, but it still plays twice sometimes.
I have run the OS in debug mode and there aren't any error messages. the debug output shows these messages when I use soundplayer:

I get these debug messages when using waveplay.exe:
