RE: Dell Inspiron 15R - 7520: Hey Cortana does not work
I have the same problem, except that it doesn`t work for me when I click the microphone icon in the Cortana textbox. It seems to listen for a second, but then it jumps to the suggestions like I didn`t say anything. I have the audio drivers for Windows 10 from the Dell support page. My voice works fine on Skype and Voice Recorder, though.
Please let us know if there is any progress.
