That's not how module loading works these days. udev loads drivers for all hardware it finds automatically. You should not need any manual configuration. In fact having alsa specific config frags in /etc/modprobe.conf.d/ can actually break your sound setup since it might bind fixed indexes to specific drivers which might then end up conflicting with automaticly assigned indexes due to hotplug. > and the driver loads fine without additional kernel options. > I noticed the tickets... > > http://www.pulseaudio.org/ticket/25 > http://www.pulseaudio.org/ticket/139 > > Could my problems be related to ticket 25 since I assume that > I am using the snd-hda-intel driver directly on the hardware?

Because there doesn't need to be any. udev should configure snd-hda-intel. And PA should find the card then automatically via HAL. The thing is that the hda driver has some issues. Make sure to install the very latest alsa-lib on rawhide (1.0.17-2) which has my patches which fixes most of them.
