Can't play a raw muLaw file through arts

I raised this question some time ago.
I have a muLaw sample with following parameters:
(it's data that came through isdn4linux's ttyI devices)
if I play the damned thing with cat sample.ulaw > /dev/sound/audio
the thing is played correctly
if I play it through a program I've written, the speed is ok, but the sample
itself sounds like the Klingons attacking "Kampfstern Galaktika". Where
silence should be I hear a lot of noise, the sounds are recognizable though.
I'm using artsc.h as API, what do I have to do in order to play the sample and
to make it sound like the original?
This is what I have:
stream = arts_play_stream( 8000, 8, 1, "artsctest" );
... read from file byte wise...
errorcode = arts_write(stream, buffer, sizeof(buffer));
... buffer is an unsigned char buffer ...
