OK  - this goes to /etc/alsa.conf

OK, I compiled alsa-drivers with Dummy as one and only card and loaded it
into the kernel:
# cat /proc/asound/card0/id
Dummy

Still no PCM in /tmp/pcm.out. I get following error messages though:
"(snd_determine_driver) could not open control for card 0"
"(_snd_config_evaluate) function snd_func_concat returned error: No such
file or directory"
"(snd_func_concat) error evaluating strings"
"(_snd_config_evaluate) function snd_func_concat returned error: No such
file or directory"
"(snd_func_refer) error evaluating name"
"(_snd_config_evaluate) function snd_func_refer returned error: No such file
or directory"
"(snd_config_expand) Evaluate error: No such file or directory"
"(snd_pcm_open_noupdate) Unknown PCM default"
"(_snd_pcm_plug_open) Unknown field hint"

Any clues?
