    Well I've been thinking about this for awhile and just attempted it and failed. Is there any way to have sound come out through the headphone AND built in speakers simultaneously?(sp?). Apparently the MIDI Setup utillity classifies the headphone and built in speakers under one category, "built-in input", and just switches depending on what is available.

    I'm not sure about this, but just in case nobody more knowledgeable chimes in:

    I think it depends on the machine. I know that the MacBooks (and I assume other recent machines) can output to both, because in some cases they did under Windows (Boot Camp), which isn't usually the desired effect. Older Macs, however, I THINK may have used a hardware "switch" to override the built-in speakers if something else was plugged in.

    I remember that under some versions of OSX if you plugged in a pair of headphones early in the boot process the Mac would panic, but that's neither here nor there... just speaks to there being a hardware signal that the Mac read to determine what was plugged in where.
