When you look at your FFT plot, is the spike nice
and sharp, or is the tip of the spike spread out
a bit ? That would be a check that "something has
broken loose" in the playback hardware. Like an
unlocked clock synthesizer.

Except if it's that, why does the one player among the several he's
tried (I think he said it was called "Billy"; I've never heard of it)
_not_ exhibit the fault (despite using, presumably, the same hardware)!
It's an odd one.

You're going to need to dig up a part number
for that thing, to find further possibilities.

(He'd probably have to open up the laptop to find that, which is usually
a tedious process. Unless you can point him at a utility that will
analyse/interrogate peripheral chips electronically.)

The desire to remain private and/or anonymous used to be a core British value,
but in recent times it has been treated with suspicion - an unfortunate by-
product of the widespread desire for fame. - Chris Middleton,
