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.)

It's called Billy Player, probably the lightest player you can get. Here is
the URL:

But the fact that it (alone, so far) plays the file correctly (in pitch) is
what is weird.

WMP doesn't, VLC doesn't, 1by1 (another simple player) doesn't. As for
other than 22.05 kHz files, I haven't tried, but I would expect them to be
off pitch, too. I haven't looked at the FFT plot, as there isn't that much
installed on it yet. (I've been spending time trying to make sure it's
clean and all drivers are up to date, since I bought it used).

I'll add this. If that one player didn't play it correctly, I think things
would make more sense! This seems to imply that this one player (Billy
Player) does something unique in rendering the 22K WAV file such that it
gets it right - go figure). And it says it is using the IDT audio under
properties.
