Donnie had asked on my previous post if I had a chance to test Skype. I just tested, and everything works very well. I didn't experience any of the choppiness that he experienced. I know that there have been several bug fixes for both PulseAudio and Alsa recently to address issues with the Intel Audio chips. For reference, my installed versions are alsa 1.0.18.dfsg-1ubuntu8 and pulseaudio 0.9.14-0ubuntu20.
I did have to make a special entry in ~/.asoundrc for my stereo headset to output to both speakers. Skype provides 8-bit unsigned mono output audio, so it needs converted to stereo if you want sound in both headphone speakers. I copied these settings from http://help.ubuntu.com here. I didn't create the launcher script they mention. Just add the following to your ~/.asoundrc and choose "skype" as your Sound In, Sound Out and Ringer device in Options->Sound Devices.
