How to enable subwoofer using headphones and Realtek HD audio drivers?

Hello,
I'm asking your help since I've bought a new Acer Aspire 4552 (windows 7 64x and ATI HD sound card with Realtek 6.0.1.6299). The problem is that the drivers won't allow me to send bass frequencies since my headphones are detected as only stereo, but when I used them in my netbook (Realtek 5.10.0.59789), my other sound card could send 5.1 sound to them and still would sound awesome. My drivers are the Realtek 2.57 January 28th 2011. Even if you could tell me... there is some way to install the Realtek 86x drivers to a 64x system?

Edit: Also I remember that for some weird reason in my old netbook I controlled the subwoofer with the Wave equalizer in XP, but I can't find it in Windows 7.

I have the same problem on an Aspire 7535G can never use the Dolby as the Subwoofer channel is not sending. but it works in PCM such a shame as i have a Sony Av amp. Did you get an answer?
