problems with recording/playing audioclips

[Martin Meili]

I haven't got any problems recording an audioclip by means of an external
microphone.

But a problem occurs when I want to play this clip by using the play
audioclip command: The sound I can hear is too fast.

If I play the same audioclip with a player and the playrate is set to 0.5
the sound (my voice) is O.K.

I'd like to use the play audioclip command.
What am I doing wrong?
