I have Windows 10 and no external mic. I can listen to the headset, but the microphone does not work. I have a Tip RIng Ring Sleeve jack. I just updated my Toshiba C55-C5241 laptop with the latest Conexant Audio Driver software.

Anyone know what to do?

Thanks in advance
@whyjack, mine has a Realtek Audio Driver. Did you try what @TairikuOkami said to use? Driver Easy Free? Also, does your PC have the Toshiba Service Station? That will also find drivers and updates for Toshiba computers. It is similar to HP's HP Support Assistant. You could also use Driverscape. But, make sure you type in your product in Google along with Driverscape. I hope this helps! :)
