After upgrading to Windows 10 my sound would keep stopping. Initially the driver would stop, but after installing latest drivers (Toshiba L750-1E8) the sound would stop, but the device manager was saying everything was working ok. As I discovered Toshiba does not support Win10 on this machine.

After downgrading back to Windows 7 Home Premium 64bit I now have the same problem. Initially I thought it a flash problems, as if I went into flash control panel and accessed my microphone the sound would come back.

I upgraded to latest version, reinstalled, uninstalled and tried an earlier version of flash. I I tried Chrome Canary, I completely uninstalled all chrome, plus all flash, uninstalled all sound drivers all to still no avail. I have run system checker and chkdsk. I also realised it was not flash as the same problem happens on silverlight running on Internet Explorer after flash and chrome were uninstalled. I have downloaded and reinstalled all latest drivers.

I have cleared temporary files / cache and removed flash folders. I have also installed Intel HDMI drivers, upgraded the BIOS. I am running full versions of AVG and Malwarebytes and these show no infections.

Help?

I have just plugged in headphones after sound stopped on laptop speakers and they are playing sound..... I had also just noticed that the sound level beside playback device (conexant smart HD) still indicates sound even after sound stopped working....

when I unplug the headphones the laptop speakers work again

Is there a solution for this?

Okay I've tried both of those... then downloaded all recommended versions of drivers for Windows 7 from Toshiba website.... the problem still persists..... Sound for a while, then suddenly stops.... If I plug in a pair of headphones sound comes through them and back to the internal speakers when I plug the headphones out again.... until the next time sound fails....

If I leave the headphones plugged in then they work without a problem.
