My original thread was for a USB microphone, then I posted this question regarding a different microphone set up here. When someone tried to help in the first thread, I asked them another question based on using a different microphone. But the two questions were not identical.
You seem to have two threads circulating on your sound/microphone question
(a) the one you are in now
"Only Getting Audio In One Ear"
dated June 5, 2013 10:25 AM
(b) "How to record audio via a USB Microphone"
dated May 5, 2013 7:03 PM
Earlier today I posted the answer to your Fill from Left and Fill from Right question in the the May 5, 2013 thread
Yes, this is getting confusing. I'm going to lock this thread.
