But speaker jacks are completely different to USB sound devices. You
cannot use them as a comparable example here.
I mean, if I've got some USB speakers which have a jack socket on the
front of them (I'm looking at just such devices right now in front of
me) and I plug in some headphones to the jack socket on my computer, I
do not expect the sound to be moved across from playing on the USB
device to my internal device and subsequently on my headphones when this
Added to this, there are numerous examples of when I really don't want,
nor would expect this to happen. e.g. I'm playing music and I get my USB
headset to make a VoIP call. My music playing happily on my USB Speakers
and I want it stay there, but as soon as I plug in my headset it
transfers. I'd much rather it stayed where it was. I may want to leave
my USB Headset plugged in (I often do).
I don't think I'm out of the ordinary here. And there are countless
other scenarios where this just doesn't work OOTB.
The general rule is if you can't do something automatically that works
every time, then don't do it automatically at all, but make it easy and
obvious to the user how to do it manually.
