No, its not like that. I am not
writing any prog. What I am trying
to point out, is that _any_ program
is affected. My whole desktop is
pretty much "speechless" these days.
Well, a few progs, like mplayer, are
unaffected (I guess they do not trust
"default" and use "hw"), but most of
anything else is broken. (and as a
most frequent test-case I use ogg123
while debugging)
Well, maybe its an asound.conf issue -
I'll attach my asound.conf... attached.
Maybe its a driver issue - I was using
snd-pcsp before and I don't remember
any problems. But now I do use snd-intel8x0,
and the results are much worse.
And this will remain so until I get an
x86_64 port of snd-pcsp, and in a mean
time I thought it would be a good idea
to get working also that. :)
Jokes aside, the difference is that
snd-intel8x0 accepts only 48000, while
snd-pcsp used to accept some other rate.

I'll answer the technical questions in
a separate e-mail. I'll try to collect
more precise info and examples.
