Trasients when playing silence with Matlab

["Lopez-Poveda, Enrique A." <ealopezpoveda@xxxxxxx>]

Dear friends,

Here is a technical question on a problem that is driving us crazy.

We want to play sounds from Matlab through an RME 
Fireface 400 sound card. The problem is that when 
we play a "silence" interval (array of zeros) we 
can hear (and even record) a clear transient at 
the onset of the _silence_ signal. We would very 
much like to get rid of that onset transient. Any 
cues as to how to get rid of it?

Thank you so much in advance.

- Enrique
