Well, not for me I have to say... I still have this "distortion/phasing"
(depending on buffer size) problem also at 48KHz with my emu10k1 SBLive.
It also happened with the others soundcards I owned: a couple SBLive
emu10k1, ForteMedia fm801, various onboard intel8x0, even with no xruns
even with every device on its own IRQ, from kernel 2.4.20 (maybe) with
lowlat+preempt patches to 2.6.x vanilla & -rt patches from Ingo Molnar
with IRQ priorities set, along various versions of ALSA and JACK from 5
years now, all built from source...
I also posted the problem (and a silly workaround that I was using :) )
on this list, and it started a thread you can read at
http://lalists.stanford.edu/lau/2005/08/0096.html

Then I bought an M-Audio Delta44 and the difference is huge. I own it
since september 2005 and the distortion/phasing problem (more phasing
than distortion, as i run it at 2x128 48KHz all the time) has happened
only three-four times maybe.
Yes, it is certainly not often. BUT, it still happens, even on this good
ice1712 card. :(

With immutated hope for the future,
