I've discovered this the hard way, i.e. after purchasing one. Setting aside the issue of whether 96 kHz is useful as a delivery format, for those of us doing audio production who mix in 96 kHz, it's always been great to be able to work on sessions with just the Macbook Pro and a pair of headphones. With this new machine that's impossible. If you look at Audio MIDI Setup, you'll see that 96 kHz is supported for the built-in speakers (strangely), but as soon as you plug in headphones or a direct line out, that option disappears. This makes it impossible to run a session in any audio program (Pro Tools, Nuendo, whatever) that's in 96 kHz, without also having to pack an external audio interface. Obviously I use an interface in the studio, but the whole idea of a laptop is that you can be portable. So with the new Macbook Pro, it seems that in addition to the dongles, I also need to carry an external interface/DAC. Could there possibly be a software fix to this or, as seems more likely, is this a cost-saving hardware issue made without the needs of pros in mind?
