Thank you Bill. I have been successful switching between mic and line, however I tried the line in suggestion and the mic was sounding very poorly. Maybe I am missing something as far as setting this up.

You mention setting Skype to take the line in, I have not found anything specifically within Skype with those kind of settings. I assume you mean the playback and record controls on my computer, which is what I tried without good success at this point.

Any suggestions on how I might get this to work using the external mixer?
