It's odd that it fails when loading module-alsa-card manually. The only
explanation that I can think of is that the card gets somehow permanently
mis-initialized if pulseaudio tries to use it too soon. Some things to test
that theory: once you have done a failed hotplug attempt, and left the card
plugged in, does it also fail if you unload module-udev-detect and load it
again? If that fails, does it fail if you restart pulseaudio (without
unplugging the card at any point)?

What about "speaker-test --channels=5 --device=surround41:1", does it work
after a failed hotplug attempt?
