Really fed up of this issue now. Sound on speakers, fluctuating, and really soft.

Question

Hey guys, I'm at my wits end now.
I bought my HP Elitebook secondhand, for a bargain. 
I reloaded Win 7, and once installed the Drivers, and once I installed, the Sound Driver, I found my speakers, are really soft, I can't really describe it, but I'll do my best, it's like the audio is flucturating,  and the bass can really be heard. I've tried experimenting with the sound options, it solves nothing. I know it's a driver issue, as when I revert back to the standard "High Definiation Audio Device". the sound is loud, clear, and has all the clarity to it, I'd expect but at the expense of system stability. 
The system becomes severly unstable, and hangs, so I think it's a driver issue, but I can't find any alternative drivers, as they all don't want to work, I've tried all revisions of the driver for this laptop, same issue, softter fluctuating audio, switch back to the generic driver, perfect, but at the cost of my stability. I was watching a movie today, and I could barely hear what was being said, due to this useless driver, and I can't find another one to try, that fixes this. This is really an annoyance, does anyone have the same issue, and have a sollution? Thanks
