I tried pavucontrol but still no sound.
I concluded there must be a conflict between also and pulseaudio
so I purged pulseaudio. This did not help.
I switched the line out cable to the onboard sound card. With
alsamixer set to the onboard sound card there sound and the volume
can be controlled with the master/front control.
With the line out cable connected to the xonar card and the
alsamixer set to the xonar card there is no sound. With pulseaudio
purged there is no signal monitor but before its deletion
pavucontrol showed the xonar connection and its signal monitor
showed a strong signal.
Conclusion: Alsamixer shows volume settings for each sound card
but does not switch to the output stream of the card, this remains
the stream from the onboard audio regardless of the alsamixer
sound card selection.
There must be another setting switch the output stream.
I also wish alsa had a signal strength monitor. Maybe I should
reinstall pulseaudio.
