 It looks like I may have to eat my words on this one.  I've just built
 and tested kernels with sources from various times this year, going back
 to March 10th (which is about as far back as I've had NetBSD on this
 laptop), and with none of them does cdplay (built mid-November) play in
 analogue mode.  That means:
 - Maybe it never worked on this machine and I was just remembering it
   working on different hardware.
 - Maybe it used to work, but the change was not in the kernel sources.
   Perhaps I inadvertantly changed something in my configuration.  In
   principle it could also be a change in the userland, but I don't see
   any suspicious changes to cdplay.c in that time window, and mixerctl
   hasn't been changed at all in the last year.
 
 Either way, I can't point to a definite regression in the project
 sources, so this PR should probably be closed.  Sorry for the noise.
 
 Meanwhile, it seems there has been some work on making cdplay fall back
 to digital mode automatically if needed.  I'll try updating to after
 those changes and see if that makes cdplay Just Work.
 
 Thanks for the feedback.
