Yes!

This machine was purchased in 6/2008, so about 3.5 years old.

The optical drive is

cd0 at atapibus0 drive 0: <HL-DT-STDVD-RAM GSA-H60N, M0084E11213,
CX04> cdrom removable

Your conjecture (about lack of hardware support for analog playback)
sounds right. If so, cdplay ought to detect it, if that's possible,
and select the correct mode itself. Or, at the very least, some better
explanation in the man page that would help the user, who typically
knows nothing of analog vs. digital transfer modes, to make the right
choice himself. Or something more explicit in the error message than
complaining about the IOCTL argument, e.g., "If you get this error,
try enabling 'digital' transfer mode".

Thanks for your help.
