I'm closing this bug, since no one else has reported anything similar,
and it was easily fixed by configuration.

Thanks to everyone who responded with their ideas.

Sound output is broken in Audacity on my Thinkpad X200 running GuixSD,
at least within GNOME 3 (I haven't tried it anywhere else).  It worked
in the past.  I see the following error messages in Audacity's
stdout/stderr:
