sound not working on toshiba satellite laptop

i also have the toshiba satellite laptop with the same no sound issue after upgrading to windows 10 from windows 8. In the past 3 days I've had first a microsoft tech then two different toshiba techs do remote sessions to resolve the no sound problem-they
each uninstalled & installed new drivers; microsoft could not correct the problem-said to contact Toshiba support for updated driver for Windows 10 - first Toshiba tech after 113 minutes of troubleshooting said it was the Window 10 driver & the Toshiba driver
were conflicting He installed the latest Toshiba driver and I had sound until I restarted my laptop this a.m. Back on the phone w. a 2nd Toshiba Administrative Tech-after troubleshooting his answer is that Windows 10 will need to be tweaked to correct this
issue. He installed a "Nanoheal" program that I can run each time to get the sound back on. This is very frustrating Who do I turn to for help now?
