NB: nrpacks parameter can be modified dynamically via sysfs.
Don't put the value over 20. Changing via sysfs has no sanity
check.
NB: async_unlink=0 would cause Oops. It remains just for
debugging purpose (if any).
NB: ignore_ctl_error=1 may help when you get an error at accessing
the mixer element such as URB error -22. This happens on some
buggy USB device or the controller.
