The Windows 10 upgrade seems to be working fine on my HDX 16 (I did a clean install).
Now I want to talk to Cortana and cannot get my built-in microphone to work. This brings up two questions.
1. Does my laptop model have an Integrated Microphone Array? I cannot remember the last time it worked, but I thought it had one.
2. If it does have a built-in mic, how do I get Windows 10 and Cortana to hear it?
I have tested and have got things to work with an external (Logitech) headset mic and headphones. And, I have an old unbranded external stand mic that works as well. I just cannot yell "Hey Cortana" at my PC and get anything to happen. I also ran the mic test on the Integrated Microphone Array and it recorded nothing (and I set the array to default).
My driver is IDT High Definition Audio CODEC 6.10.6225.0, dated 7/21/2009.
