Thank you, dflat, yes, it works now, thanks to your help! Indeed I had followed the question mark, but as you assumed: the german translation says something like "switch background audio" which I took to say "switch it ON". But now, after switching it off, it works. Great. I did not expect this from my ordinary iPod... (iPod touch, bought last summer, so the one before the actual edition...).
