Yes it's this kind of distorsion. But the problem is
that it's not here from the begining it seems to come
after some minutes of usage. I say 'seem' because I do
not have enough usage of my freshly built linux system
to be sure.
But during 2 days I use xmms to listen to a shoutcast
radio (128kbps/44khz). After some time (I would say
maybe 15 minutes) the sound quality begin to change.

My current mixer set for PCM and Master are at 94%, I
will try to lower it (but I've already tried that when
the sound was distorded to see if it changes something
with no luck). 

All my sound playback uses KDE's arts if it can helps,
except XMMS which uses /dev/dsp
