Why does my Cortana voice only work on Bluetooth devices?

Cortana voice only works on Bluetooth device

Hello,

I recently connected my Lumia 925 to a bluetooth receiver in my car. The Cortana voice assistant works fine there. However, when I am not connected to the BT device (and have BT disabled or even enabled but disconnected), Cortana does not respond to voice commands. It "listens" for a few seconds, but acts as if it can't hear anything, then just exits.

Any advice? This is on the latest Cyan update on AT&T network.

Thanks for any tips!

Have you done a power off, power on? This should reset the input source. You can also try hooking up a mic into the 1/8th headphone jack, then removing.
