Can't see the webcam under Imaging Devices in the Device Manager. Not the only one I believe but cannot find a solution. Also the built in microphone is not working (yet the combined headphone/mic does work with an appropriate headset). It's an issue since upgrading to Win 8.1, which I must admit I didn't do according to the Vaio support site (to run Vaio Update prior to upgrading) but the webcam did work prior to this. I get the impression from comments around the web that the webcam+mic is a combined device which is connected internally via USB, and is maybe getting identified incorrectly by Microsoft. If this is the case, how does one 1) correctly identify the device and 2) get it working? Thanks for any pointers.
