exactly! That is what is causing the issues. From what I can see, it
is like it was explained before. The OS has chosen to play nice and
request that the speakers are disabled.
The power requirements will not affect the system until the speakers
are producing sound. In other words, the system will only draw UP to
the power input rating while in operation. At idle, I'd wager they may
only use 1/10 of its power rating for the idle ICs and a power LED.

Only it's not the speakers that have their operation interrupted, JUST
the keyboard (not even the mouse is affected).
Hi,
I don't know if my issue is related to the one debated in this
thread, but I just recently bought myself a pair of externally (regular
power supply; no USB power) powered speakers, that plug into the sound
card as usual, but when the speakers are powered up or down, my USB
mouse disappears for a few seconds! It happens every time, and the mouse
has its resoution reset. It's no big deal to me, but I'm a bit puzzled
as to how the simple sound card connection could reset a USB connection.
I'm not trying to hijack this thread, just thought the issues might
be related.
