I looked at your profile on my machine and think I found the problem... Here's a JPG of your configuration for stereo music:

You'll notice that the crossover is 35 Hz and the LFE lowpass filter is 35 Hz. Unfortunately what you've done isn't really correct setup. By kicking in the Low-pass at 35Hz, you've diminished subwoofer right in the crossover region. This would effectively give you not much output from the subwoofer. Try resetting the LFE lowpass to at least 70 Hz, ideally 140 Hz. You created what I call cascading crossovers and that is never ideal.

Also, 35Hz is a fairly low crossover I would consider raising it to 50Hz or so. Some experimentation is merited. Your rear speakers for music are defined as large, you should redefine those to small as well. In addition, click the "All subwoofers are THX Ultra2 approved, or flat to 20Hz" check box.

Those are the things I noticed in the config file.

FYI, your 2-channel Movie and Multichannel Movie configurations looked fine.

Best,
