The headphone jack also requires the cooperation of the OS to function

  an OS cannot deny an analog jack. An OS can however deny an digital adapter.
  - zepto 10y ago
    Not true. The os switches off the analog jack when the internal speaker is used or when sound is routed to a Bluetooth headphone or speaker. Clearly the OS can deny an analog jack.

      my point is, an os can check whether an analog jack is authorized to work or not, an analog jack is an analog jack. On the other hand, a DRM system can be implemented with any digital accessory.

        Also not true - there is no reason they couldn't implement a digital handshake over 3.5mm jacks to identity approved devices. It's just wires.

    Yes it can. I can use the mixer now to mute only the analog output while the digital output (eg. HDMI) continues to play.

    iOS can refuse to play anything it fancies. If Apple wanted to add DRM it could have done it already (I thought it did once but took it off but I may be recalling incorrectly). I can't for the life of me see how this makes any difference. BTW I don't mean this as some sort of "Apple are too nice to do this" thing. TBH I think they don't enforce audio DRM largely because they wouldn't be the beneficiaries. If and when that changes then I'm sure we'll hear different rhetoric.

      They limit their market to only those people who'll put up with DRMd music. I don't recall the dates of the decisions and changes too well but I'm pretty confident iTunes sales would have sky-rocketed some time AFTER the DRM came off. Is the number of people who only buy music from iTunes really enough to keep iPhone where it is in the market?

        > Is the number of people who only buy music from iTunes really enough to keep iPhone where it is in the market? I'm going to take a punt and suggest that the answer is no. Why do I think that? Because Apple haven't restricted music to DRM only.

        Apple was the one that forced the hand of the record companies to eliminate DRM requirements. Removing the headphone jack sucks, but the reasons given are not why.

  Yes, but it cannot detect which specific device is connected to the jack and act accordingly.
  - zepto 10y ago
    Also not true - the analog jack is bidirectional, so there is no reason that devices should not be required to handshake when plugged in.
    - Elrac 10y ago
      I believe you're wrong about that. A headphone socket can report whether there's a jack plugged in or not - that one bit of information is the total extent of traffic in the reverse direction. There is no electronic standard for back talk from analog audio devices, and it would be pointless for Apple to try, because no analog device currently on the market would comply with it.

        Not really, considering it's the same port used for microphone input, playback controls, and third party devices use it for communication already...

        Pretty sure the old iphone jack works both ways as you can use it to connect a microphone. That's how those stripe card readers work, sending "modem noise" into the phone: http://www.instructables.com/id/Read-any-magnetic-strip-card-with-a-Square-reader-/ http://www.instructables.com/id/Read-any-magnetic-strip-card...

        I'm not wrong. Apple could implement a new standard for handshaking. Only approved devices would implement it or identify themselves correctly. Current analog devices would be treated exactly as they will be using the adapter shipped with the iPhone 7.

  While true, when the jack was the main interface for earplugs, it would've been unthinkable for the os to refuse routing audio there. Now that lightning is default and the adapter is an extra legacy, it's much more "reasonable" (in heavy quotes) to just pop up a dialog with "this accessory is not compatible with the media file"
