I tried looking all over for an answer, but couldn't find it. Basically here's the problem. The sound on my laptop speakers works fine, then it just cuts off at a random point. It won't work again unless I plug in then plug out headphones (or go to Control Panel -> Sound, then disable the driver and re-enable it). Then the speakers start working again, just to repeat the same process in a few minutes. It's been really annoying. However it works perfectly on headphones, no sound disappearing.
Oh and just to add, the sound in the Control Panel -> Sound shows as playing although there is no sound coming from the speakers.
I tried installing and uninstalling the driver, installing different version of a driver, but to no avail. So far the solution has been to have headphones plugged in all the time, but I'd prefer the sound from my speakers.
Since the sound on headphones works perfectly, I guess it's not a hardware problem. But if it's not a driver problem as well, why don't the speakers work properly on any driver? What should I do?
Drivers are Conexant Smart Audio HD on a Toshiba L755 laptop, using Windows 7 Ultimate 64 bit. The problem started showing up few months ago for no apparent reason.
I guess the only thing left is to reinstall the Windows entirely...
