Almost certainly not, because not a single line of code in the mixer has
changed since my fixes.
My guess is your problem is yet something else than what I fixed.
Dunh... Well, do you not get the "ghost sweeps"? If you use (the
default?) 48000 sampling, and play sweep44100.wav (in a reasonable audio
system -- it's not that prominent through my laptop speaker, though still
audible), do you not hear a lot of crackles and fainter sweeps in the
background (that actually go up ''and'' down)?
And as before, if I reset sample rate to 44100, that file plays cleanly,
but sweep48000.wav has the ghosts.
I made sure I had an absolutely standard hrev49993. I do have the custom
HDA that lets me adjust buffer size, but I removed that and used the
packaged one.
I assume I'm correct in assuming that everything ''after'' the mixer must
be at the system sample-rate? So it can't be an audio hardware problem.
Let's see if we can track this down, because it definitely makes sample-
rate conversion unusable.
