Hello.

I'm having a bit of a problem after I reset a Toshiba Satellite C55D-A-13T computer and upgraded it to windows 10. I reinstalled all the software from the Windows 10 upgrade Toshiba page and everything appears to work except the internal microphone. It doesn't appear to register any sound. It worked before, with windows 8.1 installed.

I tried another external microphone and that work fine. I tried reinstalling the IDT sound drivers and uninstalled DTS sound and Toshiba audio enhancements. I tried different audio levels and boost levels. The newest BIOS is installed. I tried using microsoft HD audio drivers but always with the same result, the green bar doesn't budge in recording devices.
