Same problem here for about one year on two Athlon configurations, one
with SB Live!, one with VT823x onboard, always running latest -CURRENT.
(usually updated 4 times a month). The distortion is not really that
bad, but it's always present, under any load. Even with 98% CPU idle, at
least a second or two every other minute the sound is not "real
time" (but not choppy, just "slow"). One can live with that, but it
would be great to get rid of it, after all that time without any
change..

By the way, Intel configuration with onboard audio (though, don't know
right now what it was), which is mostly a clone of the OS used on two
Athlons mentioned above doesn't show these symptoms. They were present
for some time near the end of 2003, but after then the sound is fine
there (at least until about half of 2004, didn't check after that, but
no one mentioned any sound problems with this one).

And maybe one more thing - with one of the Athlons (the SB Live! one),
the distortions were present during earlier 2003 with FreeBSD 4.x too.
The symptoms were not the same and not that much visible, but still
present from time to time. Without any load, of course.
