[clug] skype hdmi error

I had never used Skype until about Friday, it had some issues finding the
headphones/mic even though other apps were using both headphones and mic
without problems.

I fixed mine by going into "Options > Sound Devices" and trying different
"Sound Out" devices with the "Make a test sound button" until I heard a
sound, then I actually just guessed the "Sound In".

Possibly the last update just broke the way "Default device" was working? It
definitely wasn't working on the defaults for me.

Dave.
