I have exactly this problem...
The laptop has an internal microphone driven off a soundmax driver, however I want to use the c270 mic as I'm hoping its position will lesson noise from the fan in skype.
- Device Manager shows the HD Webcam c270 with no warnings, says its working ok and is the latest 13.10.1216.0 driver version
- However if I go to Sound and Audio Devices Properties the Sound Recording default device only shows the laptop SoundMAX HD Audio and the c270 doesn't appear on the drop down
I have left the use only default devices unticked
I have disabled and reenabled the device
I have disabled every other audio device
I have re-installed from CD (twice)
I have plugged and replugged in all USB ports
and I have now run out of options, any ideas?

I have a possible solution for you. In the Device Manager, under the category "Sound, Video, and Game Controllers" do you see an unknown device or even USB audio device listed? If so, please right-click on the device and select Update Drivers (search automatically). If there were no updates detected, please repeat the process only this time selecting Uninstall. Once your device has been uninstalled please right click the category title and select Scan for Hardware Changes.

I don't know if this was ever resolved, but when I bought the C270 HD webcam, It wouldn't install the microphone on my 64-bit Win 7 machine. I installed the software, windows installed the image and video drivers with no problem, but wouldn't install the sound driver for anything!!! The most aggravating thing about it was when I did an "update driver" it told me I had the best driver installed already! After a quick discussion with Logitech Support, he suggested that I make sure I had the native driver "wdma_usb" installed. Sure enough, that was it.
So here is what I did to fix it:
Apparently, the C270 requires a driver named "wdma_usb.inf". When I looked in my "inf" directory (C:\Windows\inf), I didn't see this file.
So, I proceeded to C:\Windows\System32\DriverStore\FileRepository\wdm
I went into the device manager and uninstalled the HD Webcam 270, scanned for new hardware and low and behold, it installed automatically with the correct driver and the webcam and microphone worked!!
Hopefully this saves somebody the 6 hours I spent finding this solution.
