The config you mean is /etc/pulse/daemon.conf :)

It shoudl also be noted that Michal does not have alsa->pulse routing by
default so it's highly likely that his alsa "default" device will be dmix.
It's interesting that the sample rates for the "card" is correctly set
to 48kHz when using dmix but will use the default of 44.1kHz when using
the hw directly.

If you could give the lspci output of the soundcard it would be useful.
I suspect that it's an alsa bug and as it's an intel device it's highly
likely that it is an HDA device.
This alsa driver does have various model=xxxxx params that can be
supplied to it which may actually help to fix the issue but I'm no
Lennart's thoughts here would probably help and give good ammo for an
Alsa bug report :)
You could also give your alsa version (cat /proc/asound/version), tho'
as Suse 0.11 is shiney and new I'd be guessing at 1.0.16.
