 The digital command does indeed let me hear the CD being played, thank
 you.  Analog mode did, however, formerly work on this machine, so I
 would argue that its failure to do so with recent -current is still a
 regression, unless analog mode has been officially deprecated.  I don't
 rebuild my base system often enough to be sure of when it stopped
 working, but I believe it was still working at the end of July and
 know that it doesn't as of the mid-November date of my latest build.
