Yes, exactly this is or better was the problem.

Fortunately it's not the only solution. See the link of Gilles (btw: Nice to 
see you here, Gilles and thanks of course ;-):
http://www.cstr.ed.ac.uk/cgi-bin/lists.cgi?config=festival_faq&entry=arunning_festival/speed.html

For documentation or archive purposes here the solution:
Put the following two lines into /etc/festival.scm
(Parameter.set 'Audio_Method 'Audio_Command)
(Parameter.set 'Audio_Command "sox -t raw -sw -r $SR $FILE -c2 -t 
ossdsp /dev/dsp")
and then restart festival with:
/etc/init.d/festival

This is perhaps something for the README.Debian of the gnopernicus package or 
better for festival?

I think this is rather a common behavior because I've got here atm three PCs 
(2 PCs and a laptop). One works (Debian woody and soundcard Creative Audigy) 
and two doesn't work (Laptop: Debian sarge and soundcard i810 or something - 
2nd PC: Debian sarge and soundcard C-Media PCI (CMI8338/8738) onboard).
