Hi Spitfire,
You're welcome and I'm glad you figured it out. Just a word of advice. Since you are using the built in sound, you will most likely experience latency (delay where when you play something and try to record it, it plays late) due to not having a real recording card in your machine.
In this situation, you could use a driver package called ASIO4ALL which will fool your stock card into thinking it's an ASIO driven card. This still eliminate any latency issues you may be having during recording. I use ASIO4ALL drivers on all my stock Dell machines that use Realtek HD cards in them. It works so well, it's like having a pro recording card in those machines. The only drawbacks are, they will not record anything other than 16/44 and of course you don't have loads of inputs to choose from.
But I definitely recommend looking into this if by chance you are noticing extreme latency, which by rights, you should since the stock cards are forced to use WDM or MME mode in Sonar. Just figured I'd pass that on to you. Good luck and I'm glad you got things working brother. :)
