YPAO can only detect the sub if it turns on and makes a sound. You can also force the sub to be on before running YPAO, but that won't solve your auto-on problem.
If turning up the sub level to the max (+10dB) still doesn't turn on the sub, you can also turn down the level on all your other speakers (by equal amounts), and then that effectively makes the sub-level higher by that amount (because you'll have to turn up the master volume to compensate for the reduced speaker levels, and that will help the sub turn on). If you have too much bass after doing that you can turn down the sub's own volume.
Post all your current speaker levels (including the sub).

I'm quite interested in this as well. I have a 3010 which I've recently mated to a Rythmik E15 (600W RMS) sub. At first I didn't know why the auto-on feature didn't appear to be working, and why I wasn't hearing anything unless I turned the volume on the sub (not gain, as I am using LFE amp inputs on the sub) to nearly 100%. I was scratching my head as to why the Yamaha just seemed to be outputting a weak signal, but after reading your comment about the low sub pre-out voltages, I guess it makes a bit more sense.
The strange thing is, with the sub volume at 50%, I ran YPAO, and the Yamaha set the gain level on the sub to -0.5. I can barely hear the sub at that level, so I have no idea what YPAO is doing... I've since set the level to about +5, and volume on the sub itself to about 60%. It's been a bit frustrating I have to admit.
On another note, I am experiencing some line noise coming from the subwoofer out. Makes my sub sound like the wind is blowing. I have since changed the way my DirecTV dish is grounded (after researching ground loop at this site), but the noise still persists. I have noticed when I touch the HDMI cable from my DirecTV DVR, to the back shield of the Yamaha, the sound changes, but still persists. Secondly, I see that the Yamaha only has 2 prongs, and no ground on it's plug. Has anyone grounded their Yamaha to other devices in their chain/wall/whatever? I might try grounding the phono-ground to my power conditioner to see if that helps at all. Any suggestions?
