Windows 7: No bass in certain appplications over 5.1 HDMI

No bass in certain appplications over 5.1 HDMI

I'm using my HDMI port with the Realtek ATI HDMI audio drivers outputting to my Sony STR-DN1010 receiver. I have a 500 watt powered polk audio subwoofer that I've been using for bass over LFE.
All was working well and everything was fine when using 5.1 mode until randomly in the middle of a movie, my system rebooted to install updates. Since then, the system will not output to the subwoofer through any applications.
Here's the weird part... When I go to my sound settings to reconfigure the device, it outputs to the sub perfectly fine when clicked for testing. But in any application like winamp or firefox, no bass.
Then to top it all off, when I open up powerDVD for a blu-ray movie, the bass is back! It's almost like all applications since the reboot have been blocked from sub access except powerDVD.
Now... I have already tried uninstalling the HDMI audio driver and installing the newest ones, no difference. Even updated the video driver (ATI) to see if that would help... Again nothing. Seems as though when I'm trying to output directly to the sub channel, all is blocked. But when I'm using stereo mode or quadrophonic, it works fine.
Any help would be appreciated... As I'm soon just going to format the thing and start over.

Sigh... I turn on bass management in enhancements and it outputs to the sub again... But weakly. It was never on before, nor was it ever needed to make the sub have sound. Such a headache at this point...
