"hydrogen -d alsa". The choices were alsa|oss|jack.  I thought that
the portaudio library was on top of the alsa (or oss) driver.

I also tried glob2.  It depends on libportaudio, produces sound and
does not allow output device selection.

By the way, ~/.asoundrc contains:
---------
pcm.!default front:Device

I tried with the other soundcard alone, and got the same results.

I noticed that the four top error messages lines about failed
expressions only appear if another application is producing sound at
the same time (namely, vlc with alsa output).
