myRIO Audio Out annoying start and end pulses

[Seitseman]

Hi,

I am writing to the audio output of the myRIO using the method discussed in this thread:

http://forums.ni.com/t5/Academic-Hardware-Products-ELVIS/how-to-play-a-sound-saved-in-myRIO/m-p/3065...

However, every sound I play includes an initial and final pulse that is more than audible. It sounds like a strong hit, and when you stream data continuously to the audio output channels, it can be quite annoying to hear the hits repeatedly.

I know that my audio data does not contain these pulses, so they must be generated by the myRIO to open and close the audio channel (well at least that is my humble guess).

I have attached the snapshots that show the pulses generated by the myRIO at the start and at the end of each sound it plays.

Thanks in advance!!

Anyone?
