with Conexant Smartaudio HD, same audio problem. Perhaps the computer needs to be made to reacknowledge the headphones. After about the fourth time, I found you can take out and put back in the headphones as you would like and the system should be back to normal. I would say to do this once every 24 hours until done. You will have to repeat this whole process exactly about three or four more times because at first when you take the headphones out the speakers come back on. This appears to readjust the sound system to the headphones. The trick is to put the computer on hibernate (go to start menu on taskbar, arrow over next to where it says shut down, then pick 'Hibernate,' the lowest option), then once it is powered off remove the battery and let the computer and battery sit separate for about five to ten minutes, then insert headphones in the jack first, put the battery back in, and turn the computer on while leaving the headphones in the jack. I had this problem for about three weeks on my Toshiba Satellite L755 laptop with Windows 7 64-bit and Conexant Smart Audio HD drivers, but it now appears to be solved. Mine doesn't seem to happen as frequently, but loses sound for long periods of time. I guess the only thing left is to reinstall the Windows entirely. The problem started showing up few months ago for no apparent reason. But if it's not a driver problem as well, why don't the speakers work properly on any driver? What should I do?ĭrivers are Conexant Smart Audio HD on a Toshiba L755 laptop, using Windows 7 Ultimate 64 bit. Since the sound on headphones works perfectly, I guess it's not a hardware problem. So far the solution has been to have headphones plugged in all the time, but I'd prefer the sound from my speakers. I tried installing and uninstalling the driver, installing different version of a driver, but to no avail. Oh and just to add, the sound in the Control Panel -> Sound shows as playing although there is no sound coming from the speakers.

However it works perfectly on headphones, no sound disappearing. Then the speakers start working again, just to repeat the same process in a few minutes. 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). The sound on my laptop speakers works fine, then it just cuts off at a random point.

I tried looking all over for an answer, but couldn't find it.
