They are now under http://rnsanchez.wait4.org/wav

Surely I'll be able to test, but only on next boot as I can't remove the
modules (device busy, but dmesg tells that the module was loaded for the
kernel (the 'kernel' module, I believe) and can't be removed).  The next boot
will happen in one of the next mornings up to (inclusive) this monday, then I
test and post the results here.

I believe the placebo effect may indeed happen with [2], but not with [1] in
this specific case, as the difference in the playback is very perceptible.

I'll be very happy if these simple tests may lead to the fixup of the audio
glitches.  :)

Regards.
