thank you very much for your hints. I finally got it working now. With 
'mplayer -ao alsa9:hw:0,2' my amplifier decodes ac3 sound, but it
contains little clicks and interruptions. I have mixers set to 100%
and no other programs using the soundcard.

When I 'insmod snd-pcm-oss snd_dsp_map=2'
mplayer -ao oss -ac hwac3 works fine, but other programs like xmms
can't play sound anymore.

Sorry if that question is stupid, but can I use other programs and
mplayer with ac3 without reloading that module?

Below I have inserted the sound-related part of my /etc/modules.conf

Thank you very much for your help!
