Hi,
Could you attach your VI please ?It will be easier for us to help you.
This problem may happen if you try to use compressed sound file. If so, try to convert your compressed sound file back.
I hope it helps.

The remedy is to use a proper waveform, not an array of 1000 random numbers. At a minimum you need to provide a dt. What that value should be is something you will need to determine based on whatever you're trying to do.

Hi Ritesh,
I agree with t06afre it is useful to convert this VI to a standard VI. You can do this by right clicking on the the Express VI t selecting Open Front Panel then click Convert. Then you'll be able to do all the modification you want on this VI.
Also I invite you to take a look at this links : Play Waveform Express VI play waveform problem

Got the same problem when I went from Windows XP to Windows 7 in my application. It seems to be with limitation on supported frequencies.
In windows XP all frequencies worked, but in Windows 7 I only managed to get some frequencies to work (e.g. 55.2kHz, 25.6kHz, 12.8kHz. and so on).
I used to play a recording from a NI-9233-card recording 25kHz.
The quick fiks is to play the 25kHZ signal with 25.6kHz (The best would be to resample it, since this quick fix will giv a sligtly higher frequency in the playback, but not a problem in my application).
