Hi Coq rouge,
No worries, I sometimes feel like I don't know any LabVIEW .
Since I don't have my 8.2 CD on me I can't test if a newer version of the OS would do the trick – something on the to-do list when I am back here.
We did think of a cute work around: use the command line to play the sound file which means we only need to use the System Exec.vi. Works fine on my end.
Thanks for the suggestions and I will post back once I have installed 8.2 on a newer version to see if that solves it (will be mid-July though).
Sincerely,
Bertrand
