Windows 7 - Can I Directly output audio from USB to 3.5mm jack?(My jack is broken)

Well my jack is broken since a few months so no joy for me... I hate it now when I can't listen to my music on my 14 speakers in my room. (NO KIDDING LOL) And today I was thinking about... HDMI... Audio?! Yes, but - I don't want to cut my only one hdmi cable which my parents use. So, I thought maybe my USB 2.0 port can emit audio, I have some spare USB cables lying to throw out, could I make it possible to connect a 3.5mm jack with the USB to the white and green cables? (USB pinout and wiring @ pinouts.ru) I don't care if it will be mono sound or stereo, I just want sound in my speakers again
Also I don't know If I had to post this in the Hardware & Devices section but I personally think this question fits better here.

P.S.: I think I'll need some software.. if yes: I am running Windows 7 Home Premium 64 bits SP1 on a Acer Aspire 5742G Intel i3 370m 2.4ghz , 4 gb ddr3 ram, ATI Radeon Mobility HD 5470 512 M GDDR3, 2 free usb ports on the right side, 1 for the mouse on the left, HDMI Ethernet and VGA on the left side (+ power source adapter which also was broken but I've fixed it).

Edit2:
Btw, I don't want to(Well.... Can't) spent any $$$ on any adaptors now...

Edit3:
Well else I will have to get the screwdriver, openup the laptop and connect some wires to the laptop speaker... But that's the last thing I want to do. If nothing else will help.

You will need an adapter.
