The modules that are loaded before the line are:
module-device-restore
module-stream-restore
module-card-restore
module-augment-properties

After the alsa sink, module-udev-detect is loaded. Module-alsa-card isn't loaded 
by the configuration file, but it's there, maybe it's loaded by 
module-udev-detect.

Please let me know if you need any other information. Thanks!
