In which way is there a problem of modconf? Modconf is there to help you
loading modules. You did load them (or maybe hotplug did load usb stuff,
whatever). If you do not load them in the right order, you have to face
a such problem. You can use modconf to unload the modules and then load
them in the appropriate order.

Sorry, you computer does, what you tell it to do. Modconf does not do
any kind of hardware detection, so it does not know that the driver
cannot play sound, only record.

Wrong. usbaudio is only a helper module, it can only be used by other
soundcard drivers to _play_ sound. If it did not work as expected in
your case, this case would still not hit the majority of the users.

Once again - who or what did load the first driver and usbaudio?
Modconf? I doubt, es1371 has nothing to do with USB.
