The whine does increase and decrease with the accelerator.

Re: Bad alternator?
 

I imagine you already know this, but I'd be under the hood,
with someone else at the wheel, the car in neutral, pushing
the gas pedal at your signal, and trying to narrow the
source down, like duckbill said. Also, I'd try to see if any
code was set, per my previous post.

Updates welcome. With all the lights coming on, I'd sure be
concerned it was a major engine component being affected.
