Svs subwoofer stopped recieving signal from av receiver.

SVS SUBWOOFER stopped recieving signal from onkyo nr656 receiver. When trying make calibration, I got an error message " check subwoofer out".
I made reset to the receiver, nothing changed.
I didn't try to see if the subwoofer plays any sound by directly connecting it to another source like smart phone via (two to one, "Y" ) cable.
I think the problem is in the AV receiver side.
All other speakers are working fine.
Assuming you connected the sub to the sub out on the receiver I think the problem is in the subwoofer since when the receiver sends a signal to the sub the mic doesn't detect the sound from the sub.
You need to connect the sub to another source to check it.
