Perhaps for some users, the auto turn on circuit on the subwoofer is set too low? Might require an adjustment of the LFE level on the preamp or the gain on the sub? Just a guess.
That could do it, I've run into that with my UMC-1/USP-1 combo, particularly with my Outlaw LFM-1 sub, and to a lesser extent with two smaller subs that take turns serving as the LFM=1's companion.
It also pays to have "known reliable" test tracks for stereo...some CDs just don't have a lot in the lower frequencies, even some that you would think would be rife with kick drum and bass guitar riffs...

Have you checked your sub woofer to see if it has a "Trigger" input jack to turn on the sub's plate amp? Do you have a cable between the UMC-200's trigger to the sub's trigger? Have you checked to see if the trigger cable is defective? Have you enable the trigger to the sub in the UMC's set-up?
My sub has an auto on circuit that was working perfectly fine on my last A/V receiver. I've had nothing but problems with the UMC-200 in this regard so I switched over to the trigger method and its still doing the same thing. The UMC-200 powers it on and off with no problem, but in between songs it will stop sending the signal to the sub. I have to manually switch sound modes to something like NEO 6 for it to come back, then back to Stereo and it will stay...until there is a gap between songs or I hit pause. When the music comes back on, the sub output is gone.
What's frustrating is its not 100% repeatable. Sometimes it works, sometimes it doesn't. I'm using an Apple TV 2 for music...don't really experience this on my other inputs, but then again the ATV2 is the only one I actually listen to music with.
Spectacle ; it would be good to know the voltage/amperage of the 200's trigger output 12v ? - its not listed in the manual . Ive noticed in the past some have less than others ;Ide check the voltage & current requirements of the subby to be switched On/Off
One example ;
I talked to Yamaha customer service today and they said that the 12v signal from their amps was only 15ma and was probably not enough to turn on the power amp. He suggested that I purchase a Niles OTI 512 which takes a small 12 input and boosts it. It would appear to work from what the websites say
Just found the 200 has a max current draw not to exceed 100ma spec so that should be plenty ;not very likely its that ..
I played a Blu-Ray audio disc. When I first tried it using the analog (7.1 setup, though I only have a 2.1 setup), no sound out of the subwoofer.
However, when I played the same disc through HDMI, I get sound from the subwoofer.
So, I know the subwoofer if working, but how can I get it to work via the analog (non-HDMI) setting?
Maybe have a look at your 7.1 analogue out settings in the bluray player. Make sure the SW/LFE is turned on. For analogue signals the UMC-200 should be passing on whatever it is receiving, no sub out indicates that it may not be receiving any.

Might want to hop into your Delorean and then give him the advice.
lol, yea ..well i found this thread while searching for the solution although found the solution elsewhere. So i figured i'd add the solution that worked for me here for future searchers that find this thread.
