No sound through speakers?

Hi all,
I usually use headphones, but thought I'd give my speakers another quick testing as I do occasionally. Unfortunately this morning when I performed a test I was unable to, there is absolutely no sound coming through the speakers or subwoofer in the laptop, however headphone sockets are fine.

I've checked my control panel settings, SB settings, and Realtek settings, they all appear to check out fine. The only two things which I can see have caused this are either:
1) When the engineer replaced the heatsink and TIM on the CPU he inadvertently disconnected any cable/cables going to the internal speaker/subwoofer?
2) The modified Realtek SB X-Fi drivers at http://forum.notebookreview.com/asu...ative-x-fi-mb-your-g73-realtek-hd-2-48-a.html have caused the speakers to no longer work, though I'm not certain why if that's the case?

Any other suggestions?

 

1) Might be.

2) I dont think it is the cause, because if it aint work it would just saying that it doesnt detect the device or such.

I think you should try to restart your laptop, and try again, or reinstall the driver all over again. And also try this one, uninstall it complete and have Windows check the problem and allow it to fix the problem to see if it work, if it doesnt, I'm sure that it will also include an explanation.

 

I see, yeah I didn't think #2 was really likely, more likely #1 by accident. I've restarted my laptop a few times today and it hasn't restored speaker sound, headphones will happily play though when connected. I'll try reinstalling the modified sound drivers, and if it's absolutely necessary I'll remove the X-Fi modified drivers and software and reinstall the usual ones to see if that does the trick, but I'd rather not do that until last resort as it wasn't easy to install originally.
