Hi Luciano,
I had the same problem, that audio playback/record was very sensitive for
xruns/dropouts.
So I tried the development kernel, (which is I found stable enough) to see
if it worked (the low latency patch is integrated in 2.6.0-test_x as you
may know), but the real problem (in my case) was IRQ sharing.
My soundcard is REALY IRQ hungry, and even moving some windows or let a
window popup did disturb the sound.
So I looked which IRQ my soundcard was using (lspci -vvv), and it was
number 9.
The same IRQ for my usb, network card, ide controller etc :-)
It's know using IRQ 5, and no dropouts at all, only a few xrun's (xruns
are detected by: "can't read from bus" errors, isn't it??) (I'm using
fps=20)
Maybe worth to have a look on it? Just a suggestion :-)
There's also a project "Demudi" which goal is to make a sound related
distribution (debian as it's bases), and one of the primary goals was: low
latency!
They probably know also a bit more about this topic.
