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 ;-):
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
and then restart festival with:
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).
