YPAO detecting non-existent subwooferfl

[kneo]

My YPAO on Yamaha 473 is detecting a subwoofer even though I don't have any connected. I am just running a 5.0 system and it keeps detecting the sub-woofer. Also, it gives me a Level error at the end of it (W-3 Level error). I've checked the polarity of all the speakers. The rear speakers are mounted horizontally close to the ceiling and angled towards the center of the room

TIA

Make sure you have subwoofer set to (none) off, and your other speakers set to large.
