Do you have another subwoofer you can connect to your system to see if it's an AVR output problem?
If not, do you have another pre-amp you can connect your subwoofer to see if the described subwoofer problem persists when connected to another functioning output device?
Maybe take the subwoofer over to a friend's house and try their AVR pre-out.
