But... what if the DRM-encumbered digital jack has an officially authorized analog adapter? That doesn't fix the DRM problem, but it does allow for the same uses as before, particularly if it also supports mini-TOSLINK for S/PDIF. Note that since S/PDIF doesn't have a compatible DRM, it's possible it would be disabled even if a jack were still present.
