There's a udevadm command for resetting/reloading the configuration,
and I'm sure I have done that successfully in the past. I don't
remember the exact command, however. You mentioned "devadm control --
reload-rules", which looks like it should do the job, but the
"Profiles" wiki page mentions a different command: "sudo udevadm
trigger -ssound".
