I wrestled with this option for more than two hours without
success.  As far as ALSA is concerned having the right card and
device on numbers 0 should be sufficient.

I then stumpled upon the Arch Linux Wiki on PulseAudio.

This command line:
pacmd list-sinks|egrep -I 'index:|name:'
lists PAs "sinks", the default is marked with an asterisk.

I don't know why PA decided to default to the HDMI output but
with a

echo  set-default-sink alsa_output.pci-0000_00_1b.0.analog-stereo > ~/.config/pulse/default.pa

I now can hear sound for instance with movies withot telling the
player which sound device to use.

Thank you very much for your patience and help.

I now want to learn what problem PA is there to solve.

Ciao, Gregor
